(1) Hardware wiring
The ON/OFF circuit of the brake is composed of the sequential output signal of the servo unit "/BK"
and "brake power supply". A typical connection example is shown below.

Note:
(1) The excitation voltage of the power-off brake is 24V.
(2) If the holding brake current is more than 50mA, please transfer it through the relay to prevent
terminal burnt out due to excessive current.
(2) Software parameter settings
For the servo motor with holding brake, it is necessary to configure one SO terminal of servo driver as
holding brake output /BK function, and determine the effective logic of SO terminal, that is, parameter
P5-44 needs to be set.
