INTRODUCTION
Product Description
The inverter drive has been developed specifically for variable speed compressors and condenser fans utilizing non-flammable refrigerants. The drive will power the compressor; control the compressor and the fan running speed; provide compressor, fan and drive protection and communicate with the master controller. The drive requires cooling and is typically installed in a system near the compressor.
Theory of Drive Operation
The primary purpose of the drive is to convert the 50/60 Hz AC input voltage into a variable frequency, variable voltage output to power the variable speed scroll compressor. The drive conditions the AC input voltage through a series of conditioning processes to arrive at the desired output. The drive first converts the AC input voltage into a DC voltage. The DC voltage is then pulse-width modulated to replicate a sinusoidal current at the desired frequency and voltage.
Agency Recognition
UL 60730-1, IEC 60335-1, IEC 60335-2-34
Nomenclature
The model number of the drive includes the power rating and nominal voltage input to the drive. See Applications Engineering for a complete explanation of the alpha and numeric characters in the drive model number.
INSTALLATION
Drive Handling
Handle and store the drive correctly to prevent damage.
• Never cut across the drive with anything sharp. Do not use a sharp blade to open the protection bag.
• Hold the drive only by the tray or edges of the heatsink. Do not hold by the components on the drive or drive accessories.
• Once opened do not stack the drives on each other.
• Use electrostatic discharge control wristbands and anti-static mats when touching the drive.
• Torque all screw terminals to 18-20 lb-in (2.0-3 N-m) to prevent any damaged to the inverter and filter board.
Mounting
The drive should be located as close to the compressor as possible, preferably within 5 feet, since the wiring between the drive and the compressor is unshielded.
Air-cooled drives are supported inside the HVAC system by an extended heatsink plate. The plate mounts through an opening in the cabinet sheet metal to expose the heatsink to the condenser fan air stream. The flange contains a gasket surface to prevent water from entering the electronics side of the control box.
The flat plate option accommodates installation to systems using the mating gas or liquid cooled cold plate heat exchanger. The cold coupling plate is designed by OEM to accommodate the system design.
There are holes in the drive mounting flange for mounting purposes. These holes will accommodate an M5 sized screw for mounting.

Pre-operation Checks
Before operating, make sure that all the wires are correctly and tightly connected. Improper connections may cause fire or electric shock.
Power On/Off
The drive should use rated AC power supply: 50/60Hz,208~240V. Use of an incorrect power supply may damage the drive. Make sure that the correct combination of a power supply and drive is used.
When powering off the drive, wait for at least 2 minutes to ensure that the drive is completely turned off.
Communication Setting
The drive is designed to be used in a master-slave configuration where the master is a system controller. Standard Modbus® protocols: RTU.
The default communication configuration displays on the rolling LED after power ON. User can write 0x1776 password to Register 200 to get access level for Reg.201 to Reg.234. By default, the drive operates in RTU mode, and the baud rate is automatically detected and adjusted based on Master devices’ baud rate.
Users can also change the slave ID. Detailed parameters and default values are in the Modbus Map (refer to Addendum).
Modbus uses a three-layer protocol – physical, data link, and application. Refer to Addendum for additional details.
o Physical Layer The physical layer defines the hardware interface to the master. The standard control interface uses a two-wire serial communication (RS485 physical layer) scheme. The recommended cable is an 18 AWG stranded copper with 2 conductors and a drain wire. The mating Molex plug part number to plug into CN15 is Molex P/N 39-01-2065.
o Data Link Layer
The data link layer defines the reliable transfer of a message transferred from the master to one of the slave devices and the reliable transfer of the response message back to the master. The drive code sets the default node address of 045 for Modbus RTU.
If the Modbus communications for the inverter is in RTU
mode, the default character framing will be a 11 bit character as follows:
• 1 including Start bit
• 8 Data bits
• 1 Even parity
• 1 Stop bit
o Application Layer
The application layer defines the type of message that will be sent and the format of the message. Read data
are available through Modbus function code 03 (0x03)
read holding registers. See Example 1.
Starting addresses 0 to 7 must be handled in a special
way: each address (at least 0 to 2) represents a
character string (up to 32 byte ASCII). In that case,
the byte count in the response frame is the length of
the string (which might be odd), and the data part of
the frame represents the string as an array of bytes
(without any kind of byte swapping). In the request
frame, the quantity of registers does not matter (and
should be set to 0).

Starting Address 2 Bytes 0x0000 to 0xFFFF
Quantity of Registers 2 Bytes 1 to 125 (0x7D)

Input Voltage and Input Current
The drives are designed for an input power supply of 208 to 240 volts 50/60 Hz. Published performance of the drive and compressor combination will have a performance tolerance specified on the compressor performance data sheet when the drive input voltage is in the range of 208 to 240 volts.
Drive Max AC Input Current
EVA3042B 18.5A RMS
EVA3071B 31.0A RMS
Power Factor Correction
The drive has active power factor correction. The drive is capable of correcting the AC input current to maximize system efficiency.
Compressor & External Fan Speed Control
The EVA3 drive supports both compressor speed & external cooling fan control. Both these controls are configured and operated separately. The speed range of EVA3 drive is from 900 RPM to 7200 RPM for compressor and cooling fan. If the speed set by the system controller is less than 900 RPM but not zero, then the compressor will work at 900 RPM. Similarly, if the speed set by the system controller is greater than 7200 RPM, then the compressor will operate at 7200 RPM. The same logic applies to external cooling fan control.
Start-up
The drive will not start with faults present. Modbus registers 78 through 85, and 1078 to 1082 should all be equal to 0. To clear faults, use "Fault Clearing" method shown below. Start the compressor using the following method:
1. Enable drive by writing '1' to Modbus register 100.
2. Write the target RPM to Modbus register 101.
Start-up control is divided into 3 stages. For a detailed description, refer to Addendum for start-up procedures and requirements. After a successful start-up, the compressor will run at the frequency that the system controller is commanding.
Shutdown
A running compressor will shut down in one of the three cases: Case I (Controlled shut down): A '0' is written to Modbus register 100 and/or register 101 depending upon control strategy. There are 3 stages to finish shutdown sequence.
Refer to Addendum for shutdown procedures and requirements.
Case II (Faulted condition): When drive faults occur, the drive will shut down the compressor. There are two types of shutdown; immediate and controlled. As per Modbus map in the Addendum, the drive trips the compressor immediately (from running frequency to zero frequency) for faults marked as “immediate shutdown.” The drive trips the compressor in the same sequence as mentioned in Case I, for faults marked as “controlled shutdown.” As mentioned above, clear faults using the "Fault Clearing" method shown below.

AE8-1435 R1
Case III (Loss of power shut down): This is un-controlled shutdown and compressor is halted in the same way as immediate shutdown sequence.
Fault Clearing
Faults will not clear unless they are commanded by system control.
To clear faults, use the following method:
1. The compressor has been shut down for at least 35 seconds.
2. The fault condition no longer exists (registers 78-85 & registers 1078-1081).
3. The drive has received a zero-speed command (register 101 = 0 & register 1101 = 0).
4. The drive has been disabled (register 100 = 0).
5. Write any “non-zero” value to register 103.
Faults will not clear unless all items above are true.
Lockout Faults
There are specific faults that will cause the drive to 'lockout' after 10 consecutive occurrences. These faults are noted in the Addendum.
These faults will not clear unless the power to the drive is fully cycled.
Stator Heat Control
In actual use, the system controller may decide whether to preheat or not according to the environment. When preheating is needed, the system controller sends register 100 a compressor enable command and register 102 a stator heating power value. The drive transmits up to 50W DC power to warm up the compressor.
The stator heating is on if the following are true:
1. There are no active errors.
2. Compressor enabled.
3. Compressor speed is set zero.
4. Stator heater power setting is from 10~50.
If the system sends a speed demand to the drive while the stator is heating; the drive will stop stator heating and start the compressor. While running, if the system sends a zero-speed command, the drive will shut down the compressor automatically, and then resume the stator heating to the value saved in Stator Heater Power Memory Register (a value or zero = off).
Status Indication
There are two controller chips on the drive; one is ARM microcontroller another is FPGA. There are two LEDs on the drive board; one is LED1 which is near the ARM microcontroller and is used for drive diagnostics, another LED is D56 which is used for indicating power status of Modbus communication.
RGB LED (LED1)
1. Blinking RED (fast) – There is a fault present on the drive
2. Blinking GREEN (slow) – There are no faults present
3. Blinking GREEN (fast) – MODBUS message successfully received
4. Solid RED – FPGA configuration failed 5. Solid CYAN – Loading new main (DSP) software
failed 6. Solid MAGENTA – Loading new FPGA software
failed 7. Solid YELLOW – Loading new boot (DSP)
software failed Rolling LED The drive has a rolling LED display with rolling text feature. a. During power on stage, the LED indicates software version and Modbus configuration. b. In normal running condition, it displays “EMERSON.” c. In fault condition, it displays fault code & name. d. The rolling LED “display speed” is configurable via Modbus. Refer to Modbus Map and Troubleshooting Sections in the Addendum for more details.
Power Interrupt
Power interrupts can result in a drive trip that won't harm the drive. The drive can withstand interrupts of short duration (<=10 ms) but will trip on anything longer.
Drive Configuration
Another feature available on the drive is the option to change communication parameters, configure the drive to use different types of compressors and sensors. Modbus registers 200-207, 211-218, 220, 221, 231, 234 serve this function (refer to Modbus Map within the Addendum for details).
These options are password protected. Register 200 must have the correct password written before any parameters can be changed. All register functions and default values are located in the Modbus Map.

AE8-1435 R1
Once configured only changes to registers 201-204 will require power cycle for the changes to be implemented.
Refer to Addendum for configuration process flow and communication settings process flow.
High Pressure Cut Out
J6 is a 2-port connector. The output is a 3.3VDC signal. The high-pressure cutout switch can be configured. The output current range for the high-pressure contact will be around 1mA or lower. To ensure correct functionality of the high-pressure switch for the system’s lifetime, typically gold-plated contacts are recommended. Refer Table-2 for detailed pinout.
This port is hardware Protected Electronic Circuit (PEC) according to IEC 60335-1 and software is Class-B.
Drive Cooling
Because of the power electronics used in the drive and the associated heat generation, drive cooling is required to keep the drive components in their design temperature range. The allowable temperature range of the drive (the ambient air surrounding the drive) -20°C to 60°C. Drive temperature should be monitored during system development at system extreme conditions to ensure that the maximum allowable drive temperature is not exceeded. The highest drive temperature will typically occur during high load conditions or high drive ambient.
The minimum recommended thermal capacity removal should be approximately 270 Watts.
Drive Over Temperature Protection
The drive is self-protected against high internal temperatures. There are different modes of protection (temperature high and foldback). For temperature high refer to Troubleshooting Table within Addendum. For foldback protection, refer to Addendum for more information.
Air Cooled Heat Exchanger
Drives cooled by the aluminum air-cooled heat exchanger are designed to be in the air flow stream of the condenser. The air-cooled heat exchanger must be installed so that the heat exchanger fins are parallel to the cooling air flow. The airflow must be a minimum of 3 meters/secs measured at the outlet of the heatsink in the direction of the airflow.
Foldback
To protect the drive components and the compressor; the compressor speed will 'foldback' or slow down to
help reduce risk to components. The foldback event(s) will be flagged in the drive's Modbus registers. This will allow the operating system to respond and mitigate the conditions causing foldback.
For further information, refer to Addendum.
Troubleshooting
The drive may indicate a fault or protection for various reasons. If a fault or protection occurs, users should power down the drive, check the drive, and check the drive running condition carefully. For the description, check and handling of these faults or protections, please refer to the Troubleshooting – Fault and Protection within Addendum
EMC Guidelines:
Install the star earth (ground) connection as close as possible to the drive. A non-coating screw is recommended for installation on the service panel to maintain a good ground connection. The star connection includes:
• System Input ground
• Drive Heat-sink ground
The use of additional ferrites and numbers of turns in the input power supply cables, compressor cables, sensor cables, aluminum shielding enclosure are optional but preferred based on system application and noise level.
Any of the input power supply cables, sensor cables, compressor cables, and communication cables should not cross or touch each other to avoid noise coupling.
Use of shielded cable is optional depending on system application, but if used, it’s mandatory to have correct connections on both sides of the cable.
