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.
● Skip frequency bands to prevent mechanical resonance effects.
The skip frequency band at speed = 0 results in a minimum speed after switching on the
motor.
● 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.
