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.
u
Observing the Drive Operation
A PLC can perform the following actions with MEMOBUS/Modbus communications at any time regardless of parameter
settings (except H5-oo).
•
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 So and from MEMOBUS/Modbus communications are
both linked by an OR operation.
u
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.
