Setpoint calculation
8.5.1
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.

Invert setpoint
Procedure
Interconnect parameter p1113 with a binary signal,
e.g. digital input 1.

Parameter
Remark
p1113 = 722.1
Setpoint inversion
Digital input 1 = 0: Setpoint remains unchanged.
Digital input 1 = 1: Converter inverts the setpoint.
p1113 = 2090.11
