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
accordingly to start and stop the converter or set the
voltage reference using MEMOBUS/Modbus communications.
