z
It only operates when multi-aux ouput terminal(DIO_41 ~ DIO_43)is set to Brake Output.
The motor brake is not opened during motor’ Auto-tuning, so be sure to open the brake forcedly when

z
About Brake opening speed, Multi-aux output terminal becomes on after passing initial excitation time
of motor and it operates with the set speed during brake opening time.
z
Brake openig current value is set as the percentage of magnetic current of motor. The brake openig
signal operates only after ocurring more output current than set value.
z
Brake closing time means the set time after multi-aux output terminal is off below the brake closing
speed. Set more high brake closing time value than decelerating time between brake closing speed and
0.

At the brake closing speed, multi-aux ouput teminal becomes off.
z
If Backlash phenomenon occurs when the motor is stopping, increase the brake closing set value more
and more until the Backlash phenomenon isn’t occurs anymore. At the same time, adjust also the brake
closing time set value.
