Macro 8 Motorised potentiometer
Only available in closed loop vector or servo operating modes.
Digital lock: The drive operates as a slave in a closed loop master-slave system. The slave motor is digitally locked to the master motor.
Shaft orientation: The motor speed is controlled in the same way as for default operation, but the motor shaft can be orientated to a specified
angular position before and/or after running the motor.
