9.1 About Optional Parts

In some applications, a servo motor is used as the generator. In that case, its regenerative energy will charge
for the power capacitor of servo motor drive and too much voltage may cause servo motor drive damaged,
therefore, that regenerative energy shall be released properly. Servo motor drive produced by our company will
release the regenerative brake energy by a power resistor.
