2.1 Wiring type

Internal terminal drawing of Servo driver for injection molding machine2.2 The main loop terminals and wiring

2.2.1: Wiring Specification1. We suggest you to use insulating cold pressure terminals and make sure firm

8

connection.2.We suggest you to use three phase isolation transformer for power supply.

2.2.2: Wiring Method1. For the input and output signal wire and encoder wire, please use the shielded one.

The length should be: input wire: within 10m; encoder signal wire: within 10m.Condition permitting, the shorter the wire is, the better.2. One end of the grounding wire should be earthed. And the diameter of the wire must

be no less than 2.5mm.3. In the environment with serious disturbance, noise filter is suggested to be installed.

While installing, pay attention to the following items：● Try to install the noise filter, the servo driver and the supervisory controller as

close as possible.● Don’t make the main circuit and the signal wires go through the same pipeline,

nor tie them together.4. Please fit a no-melt circuit breaker(NFB) to cut off the external power supply when

there’s a trouble in running., for example, air switch.2.2.3 Cautions1.match the wiring of U、V、W with terminal U,V,W respectively. You can not make

the motor run backward by changing the wiring of three phase terminals.2. Because of a lot of electrolyte and capacitance in the servo drivers, there is still high

voltage in the internal circuit even if the power is off. So please electrify servo driversfive minutes later.3. Please cut off the power supply if you don’t use the machine for a long time.4. Definition of rotating direction: Facing the machine shaft, rotating shaft rotating in ananticlockwise direction is called Forward Rotation; on the other hand, it is BackwardRotation.2.3 Terminal2.3.1: The main loop terminals

There are no shocks in this system, the largersetting as much as possible.6、Feed forward set Methods: The speed can be fed through the open-loop control of theservo system to accelerate the speed of response, when speeding up the feed forwardgain to reduce the accumulation of position loop error, thus speeding up the error rate ofcompensation .In theory analysis, the current speed gain increases, the smaller the totalerror value of location loop, that is, the smaller the integral role. But too much feedforward gain easily lead to oscillations and location overshoot, In addition, the actualsystem in the ideal differential link doesn’t exist, so the link can not gain too much, atthe same time, in order to ensure accuracy of the positioning servo system, integralcontrol is essential points

Chapter 4 Installation and adjustment for injection machine4.1 NoticeTo ensure stabilize work for servo pump, please attention to these following notice.Servo motor working process will be repeated on the state of the high-speed stop, easy

to cause the motor shaking and vibration, please ensure that motor fixed installation,reasonable firm, can use block rubber pad to fix.4.2 Notice for sensor installationIt appears repeated sucker-oil filling condition during servo pump running,it easilycause instantaneous no oil for tubin, on this basis, to ensure internal of pressure sensoralways keep hydraulic oil, please ensure oilmouth vertical installation for pressuresensor.

4.3 About unloadRelated parameters: Pr85.（Discharging pressure reverse speed）

Notice:Pr85.（Discharging pressure reverse speed）Because discharging pressure too fast, it willcause reversal noise for oil pump.Experience point:Pr85.（Discharging pressure reverse speed）＝-300About lowest pressure and the bottom flowRelated parameters：Pr168=5.（lowest pressure without work）、Pr169=20.（the bottomflow）In general, you need to keep the lowest pressure and the bottom flow, in order to ensurethat the oil ircuit filled with charge oil, prevent oil filling or putting repeatedly, leadsunstable running for injection molding machine4.4 Computer knowledgeThere are two kinds of pressure flow signal output by computer for machine:1：Theoutput signal of injection machine by computer is PQ valve signal, that is the outputcurrent signal,and it needs current and voltage transfer board, namely “Valve signalsegregation board”,because servo only accept voltage signal.

2: The output signal is 0-10V voltage signal by computer for machine, so you can directconnect with servo drive or through signal segregation board to eliminate interference .4.5 About wiring instructions for servo to injection molding machine1) Whether single or multiple pump system, a system can be divided into major loopand control circuit parts.We suggest you install interlayer between two parts, becausethe major loop will cause noise radiation2）Servo driver and filter must be installed in the same installation board And must beinstalled with the board at the area of as far as possible the metal to metal good contact3）The attachment of interference suppression filter to servo driver must be on bothsides of the shield connection, usually no more than 50 cm length.Servo drive boardmust be accepted as neutral connection of the whole machine system grounding andshieldin connectionIf the motor or other system components cause interference, so the high frequencyconnection of these parts is not good. In this case, you must implement equipotential

connection4）For connected screen layer of motor junction box ,we usually use metal cable pipe,shielding layer must through the cable wiring unit directly connected to earth pointThe leakage current will increase for use of interference suppression filter.Due to thevalue more than 3.5mA, so we should have all the following measurements:5）The minimum protect conductor sectional area was 10mm2 copper wire.6）If use into line reactor, so must be installed in the power supply side of interferencesuppression filter.7）Shielding layer must connected to shielding row, so as to reduce shieldingimpedance8）If shield layer through wire grounding, the effect of eliminating interference willpoor70%9）When using the shielding signal lines,always connect with twisted-pair cableaccording to drawn into pairs10）The premise of safety operation of driver must be strictly according to the followinginstructionsThe phenomenon of operation fault and damage might arises from improper

installation wiring*Attention to voltage abd motor rated voltage.* Don't connect power lien and motor power line by mistake；* Main circuit wiring and control circuit wiring should separate (distance > 15 cm)

* The control line is shielded/wire.Shielding layer must be grounded in the signel sideof driver

* Logic and analog input is only applicable to low voltage circuit, please useappropriate control components；* Confirm servo driver and motor shell are good grounding. motor cable shielding layershould connect both ends of between inverter and motor, when necessary, can cut offpaint*Connection of braking resistance should use shielding/twisted-pair cable (Thegrounding of shielding layer should in the single side of servo driver* Connect electric cabinet or system neutral with shortest cable to total ground end (toprevent ground loop)*In order to achieve a low impedance high frequency connection, and ground, shieldinglayer and other metal connection (for example: install board, install parts) must installwith the metal to metal contact in good condition, contact surfaces as far as possible big,the usage of grounding cable section area as far as possible big (minimum 10 mm2) oruse thick grounding row* Shielding layer for copper or tin shielding line of shielding network because steelbraided line is not suitable for high frequency range. Usually the shielding layerpressure against with clip or cable, and fixed in potential row or PE grounding. It isforbidden to use wired extend shield, and shall be directly connect shield layer to theappropriate contacts.*If use external interference suppression filter, it is better for install closed interference

43

place（<30cm）,and keep large metal areas with installation board as far as possible.* All wiring try to short, grounding try to close, and keep active for activities cable.Keep wiring flat (don't pierced), to protect two sides installation of conductor without adesignated wire* Please use glue line for outer shielding wire to prevent general interference

Appendix 1:About EMC（The electromagnetic compatibility）instructions1 DefinitionThe electromagnetic compatibility is refers to the operation of electrical equipment inelectromagnetic interference environment, no interference for electromagneticenvironment and can achieve its stable interference.2 EMC standard introductionsAccording to the national standard GB/T12668.3 requirements, servo driver needs tomeet two requirements of electromagnetic interference and anti electromagneticinterference.

56

Our existing product execution is the latest international standards:IEC/EN61800-3：2004 (Adjustable speed electrical power drive systems part 3:EMC requirements andspecific test methods),equal to national standard GB/T12668.3.IEC/EN61800-3 investigates mainly from the electromagnetic interference and antielectromagnetic interference in two aspects of the servo drive,the test ofelectromagnetic interference, mainly to the servo driver radiation interference、conducted interference and harmonic interference(corresponding to civilian servo drivesrequirement). Anti-electromagnetism interference tests emphasize on testing oftransmission resistance、radiation resistance,surge flexibility,pulse flexibility of rapidmutation ,ESD flexibility and low frequency flexibility of power (specific test projectare: 1 Immunity test for input voltage sag, interrupt and change; 2 Commutation gapimmunity test; 3 Immunity test for harmonic input; 4 change experiment for inputfrequency; 5 Unbalance tests of input voltage; 6 fluctuation test of input voltage).Strictly test according to the IEC/EN61800-3, Please operate the machines strictlyfollowing 8.3,It has better electromagnetic compatibility in general industrialenvironment3 EMC guidance3.1 Harmonic influenceThe higher harmonic ofpower will damage servo drive. In some poor quality power grid,we suggext you to install a ac input reactor3.2 There are two kinds of electromagnetic compatibility and installation matters,One interference is for electromagnetic noise surrounding environment to servo drive,another interference is servo drive to surrounding equipment.Install CautionServo 1）The drive and other electric products grounding wire should be well grounded;2) Input and output power lines and weak electric signal lines for servo drive (such as:

control circuit) try not to parallel decoration, if necessary,using vertical layout ;3）Output power lines of servo drive should use shielded cable, or use of steel eshielding power lines, and it is reliable grounding, for interference lead,we suggestusing double ground shielding line, and reliable grounding;4）For the length of motor cable is more than 100 m, requiring output filter or reactor3.3 The treatments for surrounding electromagnetic equipment to servo driveinterferencesThe general reason for driver to produce electromagnetic influence that there areplenty of relay, contact device or electromagnetic brake nearby.If there are wrong actionfor servo drive for this reason,please use the following methods to sove:1）Install surge suppressor on the disturbance of the device;2）Install filter on output side of servo driver,refer to 8.3.6，then operate；3）For leads between servo driver control signal line and testing ling,suggest usingshield cable and reliable grounding.3.4 The treatments for servo drive to surrounding equipmentsThis part of the noise is divided into two kinds: one kind is servo driver radiatedinterference, and the other one is a servo driver ransmission interference The twointerference makes surrounding electrical equipment by electromagnetic or electrostaticinduction and cause false action for equipment

57

According to several different kinds of interference, reference to the following methodsto solve:For measuring instrument, receiver and sensor , 1）in general, signal are faint, if it isclose or in the same control od servo drive, easy to be disturbed and do false actionPlease refer to the following suggestions:As far as possible from interference sources; Don't decorate or equal bandingl signallines and power line; use shield cable for leads or power line, and reliable grounding;install graviation ferrite in the output side of the servo drive（choose inhibitionfrequency in 30 Hz ~ 1000 MHz range），and round 2～3 turns，For bad conditions, canchoose EMC output filter;2） If interference equipment and servo driver using same power supply, causeconducted interference, if above method also can't eliminate interference,you shouldinstall EMC filter between servo driver and power supply (refer to 8.3.6 to selectoperation);3) Separate grounding of peripheral equipment, can eliminate leakage currentinterferencefor servo driver altogether grounding

3.5 Leakage current and processingThere are two types of drive current leakage: one kind is to the leakage current; ;Another is leakage current between line to ine.1) Influence factors and solutions of floor drain currentDistributed capacitance exists between wire and arth, greater capacitance, greatercurrent leakage; Effectively reduce distributed capacitance between servo driver andmotor distance

greater carrier frequency, greater leakage current.You can reduce leakage currentthrough redueing carrier frequency.But it will leads greater noise of motor by reducingcarrier frequenc, Please note that .The effective way by installingl a reactor for solvingcurrent leakage.Current leakage increases with increasing loop current, bigger motor, correspondinglyfor greater leakage current.2）Current leakage factor and solution between LinesOutput cabling of Servo driver has distributed capacitance, if circuit current containshigher harmonic, it could cause resonance and produce leakage current, and if usingthermal relay may cause wrong action.The solution is to reduce carrier frequency or add output reactor,It is recommended touse electronic over-current protection function for servo drive3.6 The attention for iinstalling EMC output filter in power output terminals1）When installing input EMC filter in power output end,we recommend using “Jianli”EMC filterform Changzho;2）Please use filter in strict accordance with ratings use; because filter is class 1 kind ofelectric , filter metal houding should be good grouding of large area with metal electriccabinet , and require good conductive continuity, or there will be to get an electricshock risk and serious affect EMC effect;3）Through EMC tests, found that filter grounding should connect with PE end for same
