4.4 Drive Monitoring
The master/client can read the drive parameters as long as Modbus communications are enabled.
NOTE:
The complete list of variables can be found in the PositionServo Programming Manual (PM94P01, PM94M01).
4.5 Controlling the Drive
Controlling the drive over Modbus is essentially identical to controlling the drive from the User’s program. The
list of variables and their functionality is identical for both User’s program and Modbus control. Refer to the
variable list in the PositionServo Programming Manual for the functionality of the drive’s variables.
4.6 Changing Drive Parameters
To change drive parameters, simply write to the appropriate register as listed in the PositionServo Programming
Manual (PM94P01 or PM94M01).
4.7 EIA-485 (RS485) Parameters
Drive variables #172-176 are EIA-485 (RS485) communication programming parameters specifically for
configuration of the EIA-485 interface.
