C.5 Regenerative Unit Operations by MEMOBUS/Modbus
The regenerative unit operations that can be performed by MEMOBUS/Modbus communication depend on regenerative
unit parameter settings. This section explains the functions that can be used and related parameter settings.
◆
Observing the Regenerative Unit Operation
A PLC can perform the following actions with MEMOBUS/Modbus communications at any time regardless of
parameter settings (except for H5-
parameters):
• observe regenerative unit status and regenerative unit 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 Regenerative Unit
Adjust the parameter in
accordingly to start and stop the regenerative unit using MEMOBUS/Modbus
communications.
