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

Extended setpoint channel

2.7 Direction of rotation limiting and direction of rotation changeover

2.7 Direction of rotation limiting and direction of rotation changeover
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.
