• Start current limiting on 3 phase motors

Function

Softstarters are electronic devices designed to enable 1-phase or
3-phase induction motors to start smoothly. The GF 9016 slowly ramps up
the current on two phases, therefore allowing the motor torque to build up
slowly. This reduces the mechanical stress on the machine and prevents
damage to conveyed material.
When the motor is up to full speed the power semiconductors in
GF 9016 are bridged to prevent internal power losses and heat build up. In
addition GF 9016 allows a softstop function prolonging the stop time of the
motor, preventing high counter torques from abruptly stopping the motor.
