7.3.7.7 Direction limitation and setpoint inversion
Description
A reverse operation involves a direction reversal. Selecting setpoint inversion p1113[C] can
reverse the direction in the setpoint channel.
Parameter p1110[C] or p1111[C] can be set respectively to prevent input of a negative or
positive setpoint via the setpoint channel. 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.
