C.6 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.
◆
Observing the Drive Operation
A PLC can perform the following actions with MEMOBUS/Modbus communications at any time regardless of
parameter settings (except H5-
).
• Observe drive status and drive control terminal status from a PLC.
• Read and write parameters.
• Set and reset faults.
• Set multi-function inputs. Inputs settings from the input terminals S
and from MEMOBUS/Modbus communications
are both linked by an OR operation.
◆
Controlling the Drive
To start and stop the drive or set the frequency reference using MEMOBUS/Modbus communications, an external
reference must be selected and the parameters listed below must be adjusted accordingly.
