Note: the working voltage of brake is DC 24V, current is about 0.6A.
In above diagram, BK signal is output from SO1, set parameter P5-34 to n.0011.
(2) Brake signal
The signal controls the brake. Do not have to connect the signal if the motor without
brake.
(3) Servo OFF delay time (after servo motor stop)
If the machine moves slightly due to gravity because of the brake has action delay time.
Please adjust the time as below parameter.
This parameter is used to set the output time from the brake control signal /BK to the
servo OFF operation (servomotor output stop).
With the standard setting, the servo will be OFF when the /BK signal (brake operation)
output. However, depending on machine configuration and brake characteristics, there is a
period from /BK signal output to brake action. During the time, motor will not output
torque, brake doesn’t brake, the machine may move slightly due to gravity. Now, we use

can output from output terminal via setting pa
34, please refer to chapter 5
