1) Wiring example of holding brake
The connector of the holding brake is of no polarity. You needs to prepare a 24 V external
power supply. The following gure shows the standard wiring of brake signal (/BK) and power
supply of the brake.

2) Wiring precautions
a. To decide the length of the cable on the motor brake side, consider voltage drop caused
by the cable resistance. The input voltage must be at least 21.6 V to make the brake
work. The following table lists brake specications of ISMH servo motors.

b. The brake shall not share the same power supply with other devices. Otherwise, the
brake may conduct false operation due to voltage or current drop resulted from working of
other devices.
c. Cables of 0.5 mm
