Appendix 1: Braking Resistor Selection
The energy generated by the servo motor in the braking state will be fed back to the DC bus of the
drive. When the voltage of the DC bus exceeds the protection range, the drive will report a bus
voltage high fault, and the excess energy needs to be absorbed by an external braking resistor.
When using an external braking resistor, please set the braking resistor resistance value and
braking resistor power correctly. The resistance value of the optional external braking resistor
cannot be lower than the recommended resistance value.
