1. The input EMI meet the requirement of C2 after installing input filters.
2. Above options are external, the customer should indicate when purchasing.
3. Do not connect C3 filters in IT power system.
D.8 Braking system
D.8.1 Select the braking components
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. As a result, the inertial energy of the motor
and load return to the VFD to charge the capacitors in the main DC circuit. When the voltage
increases to the limit, damage may occur to the VFD. It is necessary to apply braking unit/resistor to
avoid this accident happens.
