MCD Modbus Module Instructions
11.6. Using the Remote Operator with MCD 500
In order for the MCD 500 to accept commands from the serial network, the soft starter must be in
Auto On mode and links must be fitted to terminals 17 and 25 to 18.
The Modbus Module must be used as an interface between the soft starter and the Remote Operator.
The DIP switches on the Modbus Module must be set as follows:
177HA543.10
The Remote Operator internal parameters must be set as follows:
Parameter 1 (RS485 network baud rate) = set to match Modbus master
Parameter 2 (RS485 network address) = unique number between 1 ~ 99
Parameter 3 (RS485 network timeout) = set as required
Parameter 4 (RS485 network protocol) = Modbus RTU
Parameter 5 (Modbus protocol parity) = set to match Modbus master
