1.3 Product Overview
A frequency converter is an electronic motor controllerthat converts AC mains input into a variable AC waveformoutput. The frequency and voltage of the output areregulated to control the motor speed or torque. Thefrequency converter can vary the speed of the motor inresponse to system feedback, such as changingtemperature or pressure for controlling fan, compressor, orpump motors. The frequency converter can also regulatethe motor by responding to remote commands fromexternal controllers.
In addition, the frequency converter monitors the systemand motor status, issues warnings or alarms for faultconditions, starts and stops the motor, optimizes energy
efficiency, and offers many more control, monitoring, andefficiency functions. Operation and monitoring functionsare available as status indications to an outside controlsystem or serial communication network.

2.4.1 Requirements
WARNINGEQUIPMENT HAZARD!Rotating shafts and electrical equipment can be hazardous.All electrical work must conform to national and localelectrical codes. It is strongly recommended that instal-lation, start up, and maintenance be performed only bytrained and qualified personnel. Failure to follow theseguidelines could result in death or serious injury.
CAUTIONWIRING ISOLATION!Run input power, motor wiring and control wiring in threeseparate metallic conduits or use separated shielded cablefor high frequency noise isolation. Failure to isolate power,motor and control wiring could result in less thanoptimum frequency converter and associated equipmentperformance.
For your safety, comply with the following requirements.
• Electronic controls equipment is connected tohazardous mains voltage. Extreme care should betaken to protect against electrical hazards whenapplying power to the unit.
• Run motor cables from multiple frequencyconverters separately. Induced voltage fromoutput motor cables run together can chargeequipment capacitors even with the equipmentturned off and locked out.
Overload and Equipment Protection
• An electronically activated function within thefrequency converter provides overload protectionfor the motor. The overload calculates the level ofincrease to activate timing for the trip (controlleroutput stop) function. The higher the currentdraw, the quicker the trip response. The overloadprovides Class 20 motor protection. See8 Warnings and Alarms for details on the tripfunction.
• Because the motor wiring carries high frequencycurrent, it is important that wiring for mains,motor power, and control are run separately. Usemetallic conduit or separated shielded wire.Failure to isolate power, motor, and controlwiring could result in less than optimumequipment performance. See Illustration 2.6.

2.4.2 Earth (Grounding) Requirements
WARNINGGROUNDING HAZARD!For operator safety, it is important to ground frequencyconverter properly in accordance with national and localelectrical codes as well as instructions contained withinthese instructions. Ground currents are higher than 3,5mA.Failure to ground frequency converter properly couldresult in death or serious injury.
NOTEIt is the responsibility of the user or certified electricalinstaller to ensure correct grounding (earthing) of theequipment in accordance with national and local electricalcodes and standards.
• Follow all local and national electrical codes toground electrical equipment properly
• Proper protective grounding for equipment withground currents higher than 3,5mA must beestablished, see Leakage Current (>3,5mA)
• A dedicatedground wire is required for inputpower, motor power and control wiring
• Use the clamps provided with on the equipmentfor proper ground connections
• Do not ground one frequency converter toanother in a “daisy chain” fashion
• Keep the ground wire connections as short aspossible
• Use of high-strand wire to reduce electrical noiseis recommended
• Follow motor manufacturer wiring requirements
2.4.2.1 Leakage Current (>3,5mA)
Follow national and local codes regarding protectiveearthing of equipment with a leakage current > 3,5mA.Frequency converter technology implies high frequencyswitching at high power. This will generate a leakagecurrent in the earth connection. A fault current in thefrequency converter at the output power terminals mightcontain a DC component which can charge the filtercapacitors and cause a transient earth current. The earthleakage current depends on various system configurationsincluding RFI filtering, screened motor cables, andfrequency converter power.
EN/IEC61800-5-1 (Power Drive System Product Standard)requires special care if the leakage current exceeds 3,5mA.Earth grounding must be reinforced in one of thefollowing ways:
• Earth ground wire of at least 10mm2
• Two separate earth ground wires both complyingwith the dimensioning rules
See EN 60364-5-54 § 543.7 for further information.
Using RCDsWhere residual current devices (RCDs), also known as earthleakage circuit breakers (ELCBs), are used, comply with thefollowing:
Use RCDs of type B only which are capable ofdetecting AC and DC currents
Use RCDs with an inrush delay to prevent faultsdue to transient earth currents
Dimension RCDs according to the system configu-ration and environmental considerations

2.4.5.5 Control Terminal Functions
Frequency converter functions are commanded byreceiving control input signals.
• Each terminal must be programmed for thefunction it will be supporting in the parametersassociated with that terminal. SeeTable 2.3 forterminals and associated parameters.
• It is important to confirm that the controlterminal is programmed for the correct function.See 4 User Interface for details on accessingparameters and 5 About Frequency ConverterProgramming for details on programming.
• The default terminal programming is intended toinitiate frequency converter functioning in atypical operational mode.
2.4.5.6 Jumper Terminals 12 and 27
A jumper wire may be required between terminal 12 (or13) and terminal 27 for the frequency converter to operatewhen using factory default programming values.
• Digital input terminal 27 is designed to receive an24V DC external interlock command. In manyapplications, the user wires an external interlockdevice to terminal 27
• When no interlock device is used, wire a jumperbetween control terminal 12 (recommended) or13 to terminal 27. This provides in internal 24Vsignal on terminal 27
• No signal present prevents the unit fromoperating
• When the status line at the bottom of the LCPreads AUTO REMOTE COASTING or Alarm 60External Interlock is displayed, this indicates thatthe unit is ready to operate but is missing aninput signal on terminal 27.
• When factory installed optional equipment iswired to terminal 27, do not remove that wiring
2.4.5.7 Terminal 53 and 54 Switches
• Analog input terminals 53 and 54 can selecteither voltage (0 to 10V) or current (0/4-20mA)input signals
• Remove power to the frequency converter beforechanging switch positions
• Set switches A53 and A54 to select the signaltype. U selects voltage, I selects current.
• The switches are accessible when the LCP hasbeen removed (see Illustration 2.19). Note thatsome option cards available for the unit maycover these switches and must be removed tochange switch settings. Always remove power tothe unit before removing option cards.
• Terminal 53 default is for a speed reference signalin open loop set in 16-61 Terminal 53 SwitchSetting
• Terminal 54 default is for a feedback signal inclosed loop set in 16-63 Terminal 54 Switch Setting

2.4.5.8 Terminal 37
Terminal 37 Safe Stop FunctionThe is available with optional safe stop functionality viacontrol terminal 37. Safe stop disables the control voltageof the power semiconductors of the frequency converteroutput stage which in turn prevents generating thevoltage required to rotate the motor. When the Safe Stop(T37) is activated, the frequency converter issues an alarm,trips the unit, and coasts the motor to a stop. Manualrestart is required. The safe stop function can be used forstopping the frequency converter in emergency stopsituations. In the normal operating mode when safe stop isnot required, use the frequency converter’s regular stopfunction instead. When automatic restart is used – therequirements according to ISO 12100-2 paragraph 5.3.2.5must be fulfilled.
Liability ConditionsIt is the responsibility of the user to ensure personnelinstalling and operating the Safe Stop function:
• Read and understand the safety regulationsconcerning health and safety/accident prevention
• Understand the generic and safety guidelinesgiven in this description and the extendeddescription in the Design Guide
• Have a good knowledge of the generic and safetystandards applicable to the specific application
User is defined as: integrator, operator, servicing,maintenance staff.
StandardsUse of safe stop on terminal 37 requires that the usersatisfies all provisions for safety including relevant laws,regulations and guidelines. The optional safe stop functioncomplies with the following standards.
EN 954-1: 1996 Category 3
IEC 60204-1: 2005 category 0 – uncontrolled stop
IEC 61508: 1998 SIL2
IEC 61800-5-2: 2007 – safe torque off (STO)function
IEC 62061: 2005 SIL CL2
ISO 13849-1: 2006 Category 3 PL d
ISO 14118: 2000 (EN 1037) – prevention ofunexpected start up
The information and instructions of the instruction manualare not sufficient for a proper and safe use of the safe stopfunctionality. The related information and instructions ofthe relevant Design Guide must be followed.
Protective Measures
• Safety engineering systems may only be installedand commissioned by qualified and skilledpersonnel
• The unit must be installed in an IP54 cabinet orin an equivalent environment
• The cable between terminal 37 and the externalsafety device must be short circuit protectedaccording to ISO 13849-2 table D.4
• If any external forces influence the motor axis(e.g. suspended loads), additional measures (e.g.,a safety holding brake) are required in order toeliminate hazards
Safe Stop Installation and Set-Up
WARNINGSAFE STOP FUNCTION!The safe stop function does NOT isolate mains voltage tothe frequency converter or auxiliary circuits. Perform workon electrical parts of the frequency converter or the motoronly after isolating the mains voltage supply and waitingthe length of time specified under Safety in this manual.Failure to isolate the mains voltage supply from the unitand waiting the time specified could result in death orserious injury.
• It is not recommended to stop the frequencyconverter by using the Safe Torque Off function.If a running frequency converter is stopped byusing the function, the unit will trip and stop bycoasting. If this is not acceptable, e.g. causesdanger, the frequency converter and machinerymust be stopped using the appropriate stoppingmode before using this function. Depending onthe application a mechanical brake may berequired.
• Concerning synchronous and permanent magnetmotor frequency converters in case of a multipleIGBT power semiconductor failure: In spite of theactivation of the Safe torque off function, thefrequency converter system can produce analignment torque which maximally rotates themotor shaft by 180/p degrees. p denotes the polepair number.
• This function is suitable for performingmechanical work on the frequency convertersystem or affected area of a machine only. It doesnot provide electrical safety. This function shouldnot be used as a control for starting and/orstopping the frequency converter.

2.4.5.9 Mechanical Brake Control
In hoisting/lowering applications, it is necessary to be ableto control an electro-mechanical brake:
• Control the brake using any relay output ordigital output (terminal 27 or 29).
• Keep the output closed (voltage-free) as long asthe frequency converter is unable to ‘support’ themotor, for example due to the load being tooheavy.
• Select Mechanical brake control [32] in par. 5-4*for applications with an electro-mechanical brake.
• The brake is released when the motor currentexceeds the preset value in 2-20 Release BrakeCurrent.
• The brake is engaged when the output frequencyis less than the frequency set in 2-21 ActivateBrake Speed [RPM]or 2-22 Activate Brake Speed[Hz], and only if the frequency converter carriesout a stop command.
If the frequency converter is in alarm mode or in an over-voltage situation, the mechanical brake immediately cutsin.
In the vertical movement, the key point is that the loadmust be held, stopped, controlled (raised, lowered) in aperfectly safe mode during the entire operation. Becausethe frequency converter is not a safety device, the crane/lift designer (OEM) must decide on the type and numberof safety devices (e.g. speed switch, emergency brakes etc.)to be used, in order to be able to stop the load in case ofemergency or malfunction of the system, according torelevant national crane/lift regulations.

3.4 PM Motor Setup
This section is only relevant when using a PM motor.
Set up the basic motor parameters:
• 1-10 Motor Construction
• 1-14 Damping Gain
• 1-15 Low Speed Filter Time Const.
• 1-16 High Speed Filter Time Const.
• 1-17 Voltage filter time const.
• 1-24 Motor Current
• 1-25 Motor Nominal Speed
• 1-26 Motor Cont. Rated Torque
• 1-30 Stator Resistance (Rs)
• 1-37 d-axis Inductance (Ld)
• 1-39 Motor Poles
• 1-40 Back EMF at 1000 RPM
• 1-66 Min. Current at Low Speed
• 4-13 Motor Speed High Limit [RPM]
• 4-19 Max Output Frequency
Note concerning advanced motor data:Stator resistance and d-axis inductance values are oftendescribed differently in technical specifications. Forprogramming resistance and d-axis inductance values inDanfoss frequency converters, always use line to common(starpoint) values. This is valid for both asynchronous andPM motors.

Par.1-30
StatorResistance(Line tocommon)
This parameter gives stator windingresistance (Rs) similar to asynchronousmotor stator resistance. When line-linedata (where stator resistance ismeasured between any two lines) areavailable, you need to divide it with 2.
Par.1-37
d-axisInductance(Line tocommon)
This parameter gives direct axisinductance of the PM motor. When line-line data are available, you need todivide it with 2.
Par.1-40
Back EMF at1000RPMRMS (Line toLine Value )
This parameter gives back EMF acrossstator terminal of PM Motor at 1000RPMmechanical speed specifically. It isdefined between line to line andexpressed in RMS Value. In case the PMMotor specifications provides this valuerelated to another motor speed, thevoltage must be recalculated for 1000RPM.
Note concerning Back-EMF:Back-EMF is the voltage generated by a PM motor whenno drive is connected and the shaft is turned externally.Technical specifications usually notes this voltage relatedto nominal motor speed or to 1000 RPM measuredbetween two lines.
3.5 Automatic Motor Adaptation
Automatic motor adaptation (AMA) is a test procedure thatmeasures the electrical characteristics of the motor tooptimize compatibility between the frequency converterand the motor.
• The frequency converter builds a mathematicalmodel of the motor for regulating output motorcurrent. The procedure also tests the input phasebalance of electrical power. It compares themotor characteristics with the data entered inparameters 1-20 to 1-25.
• It does not cause the motor to run or harm tothe motor
• Some motors may be unable to run the completeversion of the test. In that case, select Enablereduced AMA
• If an output filter is connected to the motor,select Enable reduced AMA
• If warnings or alarms occur, see 8 Warnings andAlarms

5 About Frequency Converter Programming
5.1 Introduction
The frequency converter is programmed for its applicationfunctions using parameters. Parameter are accessed bypressing either [Quick Menu] or [Main Menu] on the LCP.(See 4 User Interface for details on using the LCP functionkeys.) Parameters may also be accessed through a PCusing the MCT 10 Set-up Software (see 5.6 RemoteProgramming with ).
The quick menu is intended for initial start up (Q2-** QuickSet Up) and detailed instructions for common frequencyconverter applications (Q3-** Function Set Up). Step-by-stepinstructions are provided. These instructions enable theuser to walk through the parameters used forprogramming applications in their proper sequence. Dataentered in a parameter can change the options available inthe parameters following that entry. The quick menupresents easy guidelines for getting most systems up andrunning.
The main menu accesses all parameters and allows foradvanced frequency converter applications.
5.2 Programming Example
Here is an example for programming the frequencyconverter for a common application in open loop usingthe quick menu.
• This procedure programs the frequency converterto receive a 0-10V DC analog control signal oninput terminal 53
• The frequency converter will respond byproviding 20-50Hz output to the motor propor-tional to the input signal (0-10V DC = 20-50Hz)
This is a common pump or fan application.

5.6 Remote Programming with MCT 10 Set-up Software
Danfoss has a software program available for developing,storing, and transferring frequency converterprogramming. The MCT 10 Set-up Software allows the userto connect a PC to the frequency converter and performlive programming rather than using the LCP. Also, allfrequency converter programming can be done off-lineand simply downloaded into frequency converter. Or theentire frequency converter profile can be loaded onto thePC for back up storage or analysis.
The USB connector or RS-485 terminal are available forconnecting to the frequency converter.
MCT 10 Set-up Software is available for free download atwww.VLT-software.com. A CD is also available byrequesting part number 130B1000. A user’s manualprovides detailed operation instructions.

b. The second word on the status line indicateswhere the speed control originates.
c. The last part of the status line gives the presentfrequency converter status. These show theoperational mode the frequency converter is in.
NOTEIn auto/remote mode, the frequency converter requiresexternal commands to execute functions.
7.2 Status Message Definitions Table
The next three tables define the meaning of the statusmessage display words.
Operation Mode
Off The frequency converter does not react to anycontrol signal until [Auto On] or [Hand On] ispressed.
Auto On The frequency converter is controlled from thecontrol terminals and/or the serial communi-cation.
Hand On The frequency converter can be controlled bythe navigation keys on the LCP. Stopcommands, reset, reversing, DC brake, andother signals applied to the control terminalscan override local control.
Reference Site
Remote The speed reference is given from externalsignals, serial communication, or internalpreset references.
Local The frequency converter uses [Hand On]control or reference values from the LCP.
Operation StatusAC Brake AC Brake was selected in 2-10 Brake Function.
The AC brake over-magnetizes the motor toachieve a controlled slow down.
AMA finish OK Automatic motor adaptation (AMA) wascarried out successfully.
AMA ready AMA is ready to start. Press [Hand On] to start.
AMA running AMA process is in progress.
Braking The brake chopper is in operation. Generativeenergy is absorbed by the brake resistor.
Braking max. The brake chopper is in operation. The powerlimit for the brake resistor defined in2-12 Brake Power Limit (kW) is reached.
Coast • Coast inverse was selected as a functionfor a digital input (parameter group 5-1*).The corresponding terminal is notconnected.

8 Warnings and Alarms
8.1 System Monitoring
The frequency converter monitors the condition of itsinput power, output, and motor factors as well as othersystem performance indicators. A warning or alarm maynot necessarily indicate a problem internal to thefrequency converter itself. In many cases it indicates failureconditions from input voltage, motor load or temperature,external signals, or other areas monitored by the frequencyconverter’s internal logic. Be sure to investigate those areasexterior to the frequency converter as indicated in thealarm or warning.
8.2 Warning and Alarm Types
WarningsA warning is issued when an alarm condition is impendingor when an abnormal operating condition is present andmay result in the frequency converter issuing an alarm. Awarning clears by itself when the abnormal condition isremoved.
AlarmsTripAn alarm is issued when the frequency converter istripped, that is, the frequency converter suspendsoperation to prevent frequency converter or systemdamage. The motor will coast to a stop. The frequencyconverter logic will continue to operate and monitor thefrequency converter status. After the fault condition isremedied, the frequency converter can be reset. It willthen be ready to start operation again.
A trip can be reset in any of 4 ways:
• Press [RESET] on the LCP
• Digital reset input command
• Serial communication reset input command
• Auto reset
Trip-lockAn alarm that causes the frequency converter to trip-lockrequires that input power be cycled. The motor will coastto a stop. The frequency converter logic will continue tooperate and monitor the frequency converter status.Remove input power to the frequency converter andcorrect the cause of the fault, then restore power. Thisaction puts the frequency converter into a trip condition asdescribed above and may be reset in any of those 4 ways.

WARNING/ALARM 4, Mains phase lossA phase is missing on the supply side, or the mainsvoltage imbalance is too high. This message also appearsfor a fault in the input rectifier on the frequency converter.Options are programmed at 14-12 Function at MainsImbalance.
Troubleshooting: Check the supply voltage and supplycurrents to the frequency converter.
WARNING 5, DC link voltage highThe intermediate circuit voltage (DC) is higher than thehigh voltage warning limit. The limit is dependent on thefrequency converter voltage rating. The unit is still active.
WARNING 6, DC link voltage lowThe intermediate circuit voltage (DC) is lower than the lowvoltage warning limit. The limit is dependent on thefrequency converter voltage rating. The unit is still active.
WARNING/ALARM 7, DC overvoltageIf the intermediate circuit voltage exceeds the limit, thefrequency converter trips after a time.
TroubleshootingConnect a brake resistor
Extend the ramp time
Change the ramp type
Activate the functions in 2-10 Brake Function
Increase 14-26 Trip Delay at Inverter Fault
WARNING/ALARM 8, DC under voltageIf the intermediate circuit voltage (DC link) drops belowthe under voltage limit, the frequency converter checks if a24V DC backup supply is connected. If no 24V DC backupsupply is connected, the frequency converter trips after afixed time delay. The time delay varies with unit size.
Troubleshooting:Check that the supply voltage matches thefrequency converter voltage.
Perform input voltage test
Perform soft charge circuit test
WARNING/ALARM 9, Inverter overloadThe frequency converter is about to cut out because of anoverload (too high current for too long). The counter forelectronic, thermal inverter protection gives a warning at98% and trips at 100%, while giving an alarm. Thefrequency converter cannot be reset until the counter isbelow 90%.The fault is that the frequency converter is overloaded bymore than 100% for too long.
TroubleshootingCompare the output current shown on the LCPwith the frequency converter rated current.
Compare the output current shown on the LCPwith measured motor current.
Display the Thermal Drive Load on the LCP andmonitor the value. When running above thefrequency converter continuous current rating,the counter should increase. When running belowthe frequency converter continuous currentrating, the counter should decrease.

Symptom Possible Cause Test Solution
Display dark / No function
Missing input power See Table 3.1. Check the input power source.
Missing or open fuses or circuitbreaker tripped
See open fuses and tripped circuitbreaker in this table for possiblecauses.
Follow the recommendationsprovided
No power to the LCP Check the LCP cable for properconnection or damage.
Replace the faulty LCP orconnection cable.
Shortcut on control voltage(terminal 12 or 50) or at controlterminals
Check the 24V control voltagesupply for terminal 12/13 to 20-39or 10V supply for terminal 50 to 55.
Wire the terminals properly.
Wrong LCP (LCP from VLT® 2800or 5000/6000/8000/ FCD or FCM)
Use only LCP 101 (P/N 130B1124)or LCP 102 (P/N. 130B1107).
Wrong contrast setting Press [Status] + Up/Down arrowsto adjust the contrast.
Display (LCP) is defective Test using a different LCP. Replace the faulty LCP orconnection cable.
Internal voltage supply fault orSMPS is defective
Contact supplier.
Intermittent display
Overloaded power supply (SMPS)due to improper control wiring ora fault within the frequencyconverter
To rule out a problem in thecontrol wiring, disconnect allcontrol wiring by removing theterminal blocks.
If the display stays lit, then theproblem is in the control wiring.Check the wiring for shorts orincorrect connections. If the displaycontinues to cut out, follow theprocedure for display dark.
Motor not running
Service switch open or missingmotor connection
Check if the motor is connectedand the connection is notinterrupted (by a service switch orother devise).
Connect the motor and check theservice switch.
No mains power with 24V DCoption card
If the display is functioning but nooutput, check that mains power isapplied to the frequency converter.
Apply mains power to run the unit.
LCP Stop Check if [Off] has been pressed. Press [Auto On] or [Hand On](depending on your operationmode) to run the motor.
Missing start signal (Standby) Check 5-10 Terminal 18 Digital Inputfor correct setting for terminal 18(use default setting).
Apply a valid start signal to startthe motor.
Motor coast signal active(Coasting)
Check 5-12 Coast inv. for correctsetting for terminal 27 (use defaultsetting).
Apply 24V on terminal 27 orprogramm this terminal to Nooperation.
Wrong reference signal source Check reference signal: Local,remote or bus reference? Presetreference active? Terminalconnection correct? Scaling ofterminals correct? Reference signalavailable?
Program correct settings Check3-13 Reference Site Set presetreference active in parametergroup3-1* References. Check forcorrect wiring. Check scaling ofterminals. Check reference signal.

Symptom Possible Cause Test Solution
Motor running in wrongdirection
Motor rotation limit Check that 4-10 Motor SpeedDirection is programmed correctly.
Program correct settings.
Active reversing signal Check if a reversing command isprogrammed for the terminal inparameter group 5-1* Digital inputs.
Deactivate reversing signal.
Wrong motor phase connection See 3.6 Check Motor Rotation in thismanual.
Motor is not reachingmaximum speed
Frequency limits set wrong Check output limits in 4-13 MotorSpeed High Limit [RPM], 4-14 MotorSpeed High Limit [Hz] and 4-19 MaxOutput Frequency
Program correct limits.
Reference input signal not scaledcorrectly
Check reference input signalscaling in 6-* Analog I/O mode andparameter group3-1* References.reference limits in parameter groupF-5# Extended Reference.
Program correct settings.
Motor speed unstable
Possible incorrect parametersettings
Check the settings of all motorparameters, including all motorcompensation settings. For closedloop operation, check PID settings.
Check settings in parameter group1-6* Analog I/O modeAN-##. Forclosed loop operation checksettings in parameter group 20-0*Feedback.
Motor runs rough
Possible over-magnetization Check for incorrect motor settingsin all motor parameters.
Check motor settings in parametergroups 1-2* Motor data, 1-3* Advmotor data, and 1-5* Load indep.setting.
Motor will not brakePossible incorrect settings in thebrake parameters. Possible tooshort ramp down times.
Check brake parameters. Checkramp time settings.
Check parameter group2-0* DCbrake and 3-0* Reference limits.
Open power fuses or circuitbreaker trip
Phase to phase short Motor or panel has a short phaseto phase. Check motor and panelphase to for shorts.
Eliminate any shorts detected.
Motor overload Motor is overloaded for theapplication.
Perform startup test and verifymotor current is within specifi-cations. If motor current isexceeding nameplate full loadcurrent, motor may run only withreduced load. Review the specifi-cations for the application.
Loose connections Perform pre-startup check for looseconnections.
Tighten loose connections.
Mains current imbalancegreater than 3%
Problem with mains power (SeeAlarm 4 Mains phase lossdescription)
Rotate input power leads into thedrive one position: A to B, B to C, Cto A.
If imbalanced leg follows the wire,it is a power problem. Check mainspower supply.
Problem with the frequencyconverter unit
Rotate input power leads into thefrequency converter one position: Ato B, B to C, C to A.
If imbalance leg stays on sameinput terminal, it is a problem withthe unit. Contact supplier.
Motor current imbalancegreater than 3%
Problem with motor or motorwiring
Rotate output motor leads oneposition: U to V, V to W, W to U.
If imbalanced leg follows the wire,the problem is in the motor ormotor wiring. Check motor andmotor wiring.
Problem with drive unit Rotate output motor leads oneposition: U to V, V to W, W to U.
If imbalance leg stays on sameoutput terminal, it is a problemwith the unit. Contact supplier.

Protection and Features:
• Electronic thermal motor protection against overload.
• Temperature monitoring of the heatsink ensures that the frequency converter trips if the temperature reaches 95°C± 5°C. An overload temperature cannot be reset until the temperature of the heatsink is below 70°C ± 5°C(Guideline - these temperatures may vary for different power sizes, enclosures etc.). The frequency converter hasan auto derating function to avoid it's heatsink reaching 95°C.
• The frequency converter is protected against short-circuits on motor terminals U, V, W.
• If a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).
• Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if the intermediate circuitvoltage is too low or too high.
• The frequency converter is protected against earth faults on motor terminals U, V, W.
