choose when purchasing accessories.
C.7 Braking resistors
C.7.1 Braking resistor 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 brake components.
The design, installation, commissioning, and operation of the device
Follow all the "Warning" instructions during the operation.
Only qualified electricians are allowed to perform the wiring.
Read the braking resistor instructions carefully before connecting
Connect braking resistors only to the terminals PB and (+). Do not
Connect the brake components to the VFD according to the wiring
