● Use the built‑in brake for position‑lock purpose only. Do not use this brake for any
other purposes (such as braking) other than position‑lock in the stop state.
● The brake coil has no polarity.
● Switch off the S‑ON signal after the servo motor stops.
● When the servo motor with brake runs, the brake may generate a click sound,
which does not affect its function.
● When brake coils are energized (the brake is released), magnetic flux leakage may
occur on the shaft end. Pay special attention when using magnetic sensors around
the servo motor.
The connection of the brake input signal is polarity‑insensitive. Users need to prepare
a 24 V power supply. The following figure shows the standard wiring of the brake
signal (BK) and the brake power supply.
Figure 3‑36 Wiring of the brake
Pay attention to the following precautions during wiring:
When deciding the length of the motor brake cable, take the voltage drop caused by
cable resistance into consideration. The input voltage must be at least 21.6 V to
enable the brake to work properly. The following table lists brake specifications of
Inovance MS1 series servo motors.
