12.7 Braking Resistor
Braking resistor protection
In applications where a braking resistor is installed, it is recommended to use a resistor
with a temperature switch to ensure safety and avoid overheating and burning of the
braking resistor. Connect the temperature switch output to the electromagnetic contactor
control circuit on the front end of the drive (as shown in the following figure) to
implement the interlock protection function. When the resistor overheats, a tripping fault
occurs, avoiding the resistor to be burned.

Selecting the resistance of the braking resistor
The built-in braking unit of the drive processes the regenerative energy generated by the
motor during deceleration. When the DC bus voltage exceeds the limit set by the
software, the braking unit automatically turns on and connects the braking resistor to the
DC bus. The braking resistor consumes the regenerative energy to keep the bus voltage
within the safe range. The braking resistor is disconnected until the bus voltage drops
below a certain range. The resistance of the braking resistor is calculated based on the
following formula.
