Braking Units and Braking Resistors
Braking units are used to absorb the motor regeneration energy when the motor
stops by deceleration. With the braking unit, the regeneration energy is dissipated
by braking resistors. Our braking units are suitable for 230V and 460V
DURA
PULSE drives, and must be used in conjunction with GS series braking
resistors to provide the best braking results.
