8.2.4 Brake Output
In order to reduce heat in the brake, connected to the motor, the driver outputs DC power to
turn off the brake.
When supplying power to the driver after connecting the driver and brake, the rated
excitation voltage is supplied and the brake power is released after approx. 1 sec.
Then after approx. 0.2 sec, the excitation voltage is decreased to 11.5VDC and the released
brake power is maintained.
※While power is supplied to the driver, the brake is kept turning on, except in the Servo On
status.
