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.
