Siemens SINAMICS G110M - Setpoint Calculation; Overview

8.17 Setpoint calculation
8.17.1 Overview
Overview
Setpoint processing in󹪞uences 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 e󹪜ects by only permitting the
motor to operate brie󹪞y at speci󹪝c 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.
