IS810N-INT Series Servo System User Manual (Brief)Chapter 4 Wiring
Caution
Use this built-in brake to keep the stalling status only. Never use this for "Brake" to stop the
load in motion.
Brake coils are of no polarity.
Turn off S-ON after the servo motor stops.
When the servo motor with a brake runs, the brake may generate a click sound, which does
not affect its functions.
When brake coils are energized (the brake is released), magnetic ux leakage may occur at
the shaft end. Thus, pay special attention when using magnetic sensors around the servo
motor.
The connector of the motor brake has no polarity. Users need to prepare a 24 V external
power supply. The following gure shows the standard wiring of the brake signal (BK) and
brake power supply.

Pay attention to the following precautions during wiring:
To decide the length of the cable on the motor brake side, consider voltage drop caused by
cable resistance. The input voltage of the brake must be at least 21.6 V.
