GF 9016
Product Description
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.
