G7 Series AC Drive

uninterruptible operation. A motor thermistor can be evaluated using an analog input and protects the motor against overheating.

In combination with a transformer with two secondary windings (star and delta), the harmonics can be suppressed using the 12 pulse method.Very fast and accurate current regulation functions support continuos operation by preventing overcurrent tripping. Power loss ridethrough, motor stall prevention and automatic restart after fault also support the

G7 drive performance makes it the ideal drive for high performance speed, torque, or position control applications. Several control modes are provided. In open loop vector mode, the latest flux observer algorithms extend speed range and provide maximum starting torque.All inverters larger than 15kW are equipped with a DC bus reactor and second rectifier bridge as standard.
