RS485/RS232 Communication Module

You can create a network of drives by linking a Master (PC/PLC) to one or more 650 drives
fitted with this module.
Plug this Communication Module on to the front of the 650 drive, replacing the keypad.
It converts signals from the host 650 drive into RS485 or RS232, and vice versa, so that
information can be shared between the Master and 650 drive(s).
Wiring is very simple - all connections are SELV (Safe Extra Low Voltage). Select to use
RS485 or RS232 by wiring to the appropriate terminal on the module.
We recommend you ground the module to the system earth using the Functional Earth terminal.
