Note:
1. The input EMI meets the C2 requirements after an input filter is configured.
2. The preceding table describes external accessories. You need to specify the ones you choose
when purchasing accessories.
D.8 Braking system
D.8.1 Braking component selection
When the VFD driving a high-inertia load decelerates or needs to decelerate abruptly, the motor runs
in the power generation state and transmits the load-carrying energy to the DC circuit of the VFD,
causing the bus voltage of the VFD to rise. If the bus voltage exceeds a specific value, the VFD
reports an overvoltage fault. To prevent this from happening, you need to configure braking
components.
