Another digital input (MPOT1-INACT) exists apart from the two digital inputs MPOT1-UP and
MPOT1-DOWN. The motor potentiometer function can be activated or deactivated with the input
MPOT1-INACT. Logic 1 at this input activates the motor potentiometer function. The input
MPOT1-INACT has priority over the inputs MPOT1-UP and MPOT1-DOWN.
