When a motor stops, the brake IGBT is used to convert kinetic energy of the motor into electric energy and to consume the energy as heat of a resistor (damping resistor). Deceleration time of the motor can be reduced when using a damping resistor. Make sure that the DC voltage does not increase too much with the regenerated energy and exceed the breakdown voltage of the electrolytic capacitor.
