Direction Of Rotation Limiting And Direction Of Rotation Changeover - Siemens SINAMICS S120 Function Manual

2.2.6 Direction of rotation limiting and direction of rotation
changeover
Description
A reverse operation involves a direction reversal. A direction reversal in the set-
point channel can be triggered by selecting direction reversal p1113[C].
If, on the other hand, a negative or positive setpoint is not to be preselected via the
setpoint channel, this can be prevented via parameter p1110[C] or p1111[C].
