Figure 3‑6 Application of the brake
● 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 motor stops.
● When the 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), flux leakage may occur on
the shaft end. Pay special attention when using magnetic sensors around the
motor.
The connection of brake input signals is polarity‑insensitive. Users need to prepare a
24 V power supply. The following figure shows the standard wiring of the brake
signals (BK) and the brake power supply.
Figure 3‑7 Wiring of the brake
Pay attention to the following precautions during wiring:
When determining the length of the motor brake cable, take full account the voltage
drop caused by cable resistance. 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.
