type designation information.
3.2 Basic principles
Goodrive300-19 series inverters are wall, flange or floor mounting devices for controlling
asynchronous AC induction motors.
The diagram below shows the simplified main circuit diagram of the inverter. The rectifier converts
three-phase AC voltage to DC voltage. The capacitor bank of the intermediate circuit stabilizes the
DC voltage. The converter transforms the DC voltage back to AC voltage for the AC motor. The brake
pipe connects the external braking resistor to the intermediate DC circuit to consume the feedback
energy when the voltage in the circuit exceeds its maximum limit.
