E.5 Drive Operations by MEMOBUS/Modbus
The drive operations that can be performed by MEMOBUS/Modbus communication depend on drive parameter settings. This
section explains the functions that can be used and related parameter settings.
u Observing the Drive Operation
A PLC can perform the following actions with MEMOBUS/Modbus communications at any time regardless of parameter
settings (except for H5-ooparameters):
• observe drive status and drive 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.
