Page 4: About These Guidelines
About these guidelines The purpose of these guidelines is to provide guidance in the application of Emerson drives in users’ systems. They are intended to answer the questions raised while designing, assembling and operating a system with these products. Besides the support they provide, the instructions listed herein are also critical for the proper and safe functioning of the compressors. -
Page 5: General Instructions
General instructions Safety risks (read carefully!) After disconnecting power, wait 10 minutes before removing the drive enclosure. Before operating and maintenance work always check that all voltages at the terminals are zero or at levels which are harmless. Always make sure the compressor has stopped completely before removing the drive enclosure. - Page 6 ▪ Ensure that the airstream over the heatsink does not influence the environment of the drive (keep pollution degree 2). ▪ No condensation under normal operation. ▪ Ensure that the cool plate for flat plate versions does not create condensation inside the drive. ▪...

Page 7: Product Description
Product description General information about the EV3 drive The EV3 inverter drive has been developed specifically for Copeland Scroll™ compressor models ZPV066 and ZPV096. These are variable speed compressors with permanent magnet synchronous motors. The drive will power the compressor, control the compressor running speed, provide compressor and drive protection and communicate with the master controller. -
Page 8: Conformity To Directives And Standards
Conformity to directives and standards The EV3 drive has been designed and developed especially for the European commercial market based on applicable European Directives. The design is qualified by main safety standards EN 60335-1 (Safety for household and similar electrical appliances, Part 1: General requirements), EN 60335-2-34 (Part 2-34: Particular requirements for motor-compressor) and EN 60730-1 (Automatic electrical controls for household and similar use). -
Page 9: Installation
Installation Handling ▪ Correct handling and storage of the drive is essential in preventing mechanical damage. ▪ The box and the protection bag inside the box have to be opened with care. Do not use any sharp object to open the protection bag or cut across the drive. ▪... -
Page 10: Mounting
Mounting The drive should be located as close to the compressor as possible, preferably within 1 meter of the compressor. To avoid electromagnetic interference please ensure that the motor cables do not cross or attach to any other connecting cables. There should be at least a natural air stream inside the cabinet and around the drive to keep the temperature below 65°C. -

Page 12: Compressor Connection
▪ Accuracy: ± 1% ▪ Powered by: Internal 5 VDC (terminal 2) ▪ Temp. range: -40 to +155°C ▪ Reference: Emerson ECN-G series The sensor should be mounted on the discharge line approx. 120 mm away from the compressor outlet. AGL_Sol_EV3_E_Rev_01... -
Page 13: Sto Input
▪ Powered by: Internal 24 VDC (terminal 4) ▪ Current flow: Typically ~10mA ▪ Reference: Emerson PS4 series Caution: Connect the safety limiter directly to terminals 6 and 7 without any relay etc. in between. Otherwise the safety will probably not be guaranteed any longer. -
Page 14: Start-Up & Operation
Furthermore, it provides an advanced register description. For the latest version of the Modbus map, please contact the Application Engineering department at Emerson. Drive configuration The drives were specially designed for the ZPV066 and ZPV096 compressors. The compressor code will be set by default, so it will not have to be introduced by the user. -
Page 15: Envelope Control
The power demand must be written in register [102]. The value represents the percentage of power (0%-100%). The maximum power that can be commanded on the stator is readable via register [52]. The relation between the power and the value introduced in register [102] is the following: ▪... -
Page 16: Active Envelope Protection
1: High-Speed Envelope Protection ▪ Overload Protection enabled. ▪ Normal Operation: the minimum speed is the minimum speed of the envelope. Value taken from the EEPROM and updated frequently based on the operating point. The user must take care to run the compressor within the envelope at all times. -
Page 17: Clearing Faults
Grey zone: ▪ Speed range: 2600-6000 rpm ▪ Allowed running time based on the evaporating temperature: o if less than -15C: 15 minutes o if higher than -15C: 30 minutes If the speed demand is less than 2600 rpm or higher than 6000 rpm, the speed is increased or decreased automatically to respect the speed range. -
Page 18: Compressor Shutdown
Figure 7: Start-up sequence Compressor shutdown The user has the possibility to perform an immediate shutdown or a controlled shutdown. By setting the compressor Enable register [100] to Disabled, while the speed demand is greater than 0, the drive will perform an immediate stop. Otherwise if the user sends a Disable command as well as 0 speed demand (insert 0 in Compressor Speed Demand register [101]), the drive will issue a controlled stop. -
Page 19: Optional Analog Board
Optional analog board The analog board is foreseen for users who do not have the possibility to control the EV3 drive via ® an RS485 communication and the Modbus protocol. To control the EV3 drive the analog board needs a digital enable signal and an analog signal to set the speed or heating demand. The drive compressor package must be selected by a 6-Digit DIP-switch. -

Page 21: Clearing Faults
Figure 10: Analog control board code selection NOTE: The binary code represents the binary transformation of the package code starting from right to left (from 6 to 1). 5.2.2 Clearing faults Faults are cleared automatically as long as the cause of the fault is no longer existing. In case of a drive fault the analog board will automatically send the clear fault command to the drive. -
Page 22: Shutdown Conditions
Based on the compressor envelope and the speed range selection (see paragraph 5.2.7 "Compressor speed range selection") it can happen that low speed demands will be ignored. 5.2.6 Shutdown conditions The drive will stop in heating as well as in running mode if one of below conditions occurs: ▪... -
Page 23: Protections And Alerts
Protections and alerts When the drive is in normal operation, the power LED will always be turned on and the fault LED will be off. In case the drive is in fault or protection mode, the fault LED will flash at 2 Hz for a specific number of times. -
Page 24: Power Module Speed-Drop Protection
Reasons for moving to the Speed-Drop Protection mode: ▪ Overtemperature of the power module ▪ Overtemperature in the discharge line ▪ Operating in field weakening range ▪ Output overcurrent ▪ Input overcurrent ▪ Drive ambient temperature foldback The controller can avoid moving to the Speed-Drop Protection mode by using registers [37], [40], [41], [42], [43], [44], [45] and [110] for control purposes. -
