2.7

Direction of rotation limiting and direction of rotation changeover

Description

A reverse operation involves a direction reversal. A direction reversal in the setpoint channel

can be triggered by selecting direction reversal p1113[CDS].
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[CDS or p1111[CDS]. However, the

following settings for minimum speed (p1080) in the setpoint channel are still operative. With

the minimum speed, the motor can turn in a negative direction, although p1110 = 1 is set.
