9-14
9-2-6 Braking Resistor Unit
H 3G3IV-PLKEBj
Use a resistor to absorb regenerative energy
of the motor to reduce deceleration time.
(Usage rate: 10% ED.)
Note “Usage rate: 10% ED” indicates that the
deceleration time can be reduced by
10% of the operating time of one cycle.
Refer to 2-2-3 Wiring around the Main Circuit
for precautions when selecting the Braking
Resistor.
