Setpoint processing

6.16.1

Overview

Overview
Setpoint processing influences the setpoint using the following functions:
• "Invert" inverts the motor direction of rotation.
• The "Inhibit direction of rotation" function prevents the motor from rotating in the
incorrect direction; this function can make sense for conveyor belts, extruders, pumps and
fans, for example.
• 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.
