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.
Table 11-1 Recommended specification of braking resistor
The resistance value and power
of the external braking
resistor can be input. The
default value is 0, which
means that the power and
temperature detection of the
external braking resistor is
not enabled.
