C.5 Converter Operations by MEMOBUS/Modbus

The converter operations that can be performed by MEMOBUS/Modbus communication depend on converter parameter
settings. This section explains the functions that can be used and related parameter settings.

Observing the Converter Operation

A PLC can perform the following actions with MEMOBUS/Modbus communications at any time regardless of parameter
settings (except for H5- parameters):

• observe converter status and converter control terminal status from a PLC.
• read and write parameters.
• set and reset faults.
• set multi-function inputs.

Note: Input settings from the input terminals (S1 to S8) and from MEMOBUS/Modbus communications are both linked by a logical OR

operation.

Controlling the Converter

Select an external reference and adjust the parameters in

Table C.2

accordingly to start and stop the converter or set the

voltage reference using MEMOBUS/Modbus communications.
