6.4.2.1 Overview
Overview
Setpoint processing influences the setpoint using the following functions:
● "Invert" inverts the motor direction of rotation.
● The "direction of rotation deactivate" function prevents the motor rotating in the incorrect
direction.
● The "Skip frequency bands" prevent the motor from being continuously operated within
these skip bands. This function avoids mechanical resonance effects by only permitting the
motor to operate briefly at specific speeds.
● The "Speed limitation" function protects the motor and the driven load against excessively
high speeds.
● The "Ramp-function generator" function prevents the setpoint from suddenly changing. As
a consequence, the motor accelerates and brakes with a reduced torque.
