    TECDrive20-EU Series Inverter Optional peripheral accessories C.7 Braking resistors C.7.1 Selecting braking resistors It is appropriate to use braking resistor or braking unit when the motor brakes sharply or the motor is driven by a high inertia load. The motor will become a generator if its actual rotating speed is higher than the corresponding speed of the reference frequency.
