Overview of setpoint processing

The setpoint can be modified as follows using the setpoint processing:
● Invert setpoint to reverse the motor direction of rotation (reversing).
● Inhibit positive or negative direction of rotation, e.g. for conveyor belts, pumps or fans.
● Minimum speed to avoid standstill when the motor is switched on.
● Limit to a maximum speed to protect the motor and mechanical system.
● Ramp-function generator to accelerate and brake the motor with an optimum torque.

Remark
Setpoint inversion
Digital input 1 = 0: Setpoint remains unchanged.
Digital input 1 = 1: Converter inverts the setpoint.
Invert setpoint via control word 1, bit 11.
