◆
Use the built-in brake for position-lock in the stop state only.
◆
The brake coil has no polarity.
◆
Cut off the S-ON signal after the servo motor stops.
◆
When the servo motor with built-in brake runs, the brake may generate clattering sound. Such
sound does not affect the motor functions.
◆
When brake coils are energized (brake released), magnetic flux leakage may occur at the shaft
end. Be cautious when using magnetic sensors around the servo motor.
The connection of the motor brake input signal has no polarity. Users need to prepare a 24 V external
power supply. The following figure shows the standard wiring of the brake signal (BK) and the brake
power supply.

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 servo motors.

NOTE
◆
The brake cannot share the same power supply with other electrical devices. This is to prevent
malfunction of the brake due to voltage or current drop caused by other working devices.
◆
It is recommended to use cables of 0.5 mm 2 and above.
