Direction of rotation limiting and direction of rotation changeover

Description
A reversing operation involves a direction of rotation reversal. Selecting setpoint inversion
p1113[C] can reverse the direction of rotation 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.
