Dold GF9016 3AC400-600V UH DC24V 18,5KW | Softstarter, Part N: 0061165

The softstarter and softstop device GF 9016 is a electronic control unit for the smooth starting and stopping of three-phase asynchronous machines. 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.
