2.13 XC Pro controller – Peripheral devices
The unit controller interacts with several devices inside the electrical cabinet. These guidelines only
provide general inf ormation about and short descriptions of the peripheral devices. Dedicated
technical documentation (manuals, operating instructions) f or those devices is availabl e at

2.13.1 Variable frequency drive EVM

The Emerson variable frequency drive EVM has been designed for applications that require flexible
integration with systems via industrial Ethernet protocols and fieldbuses, together with advanced
RFC-A open-loop motor control. Connection to RS485 networks using Modbus RTU allows for
communication with the unit controller.
The EVM f requency inverter uses the input signal of the controller to adjust the compressor speed
to the requirements. For more details see the EVM Inverter handbook.
