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.

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.
● Use cables with a cross‑sectional area above 0.5 mm
