Linear Servomotors: The times required to brake depend on the brake that you use. Set the parameters related
to /BK signal output timing according to the delay times for the brake that you will actually use.
*2.
Before you output a reference from the SVD to the Servo Section, wait for at least 50 ms plus the brake release
delay time after you turn ON the servo.
*3.
Use the following parameters to set the timing of when the brake will operate and when the servo will be turned
OFF.
• Rotary Servomotors: Pn506 (Brake Reference-Servo OFF Delay Time), Pn507 (Brake Reference Output
Speed Level), and Pn508 (Servo OFF-Brake Command Waiting Time)
• Linear Servomotors: Pn506 (Brake Reference-Servo OFF Delay Time), Pn508 (Servo OFF-Brake Command
Waiting Time), and Pn583 (Brake Reference Output Speed Level)
Connection Examples

/BK (Brake Output) Signal

The following settings are for the output signal that controls the brake. You can change the
connector pin that is allocated. For details, refer to Allocating the /BK (Brake Output) Signal.
The /BK signal is turned OFF (to operate the brake) when the servo is turned OFF or when an
alarm is detected. You can adjust the timing of brake operation (i.e., the timing of turning OFF
the /BK signal) with the servo OFF delay time (Pn506).
Type
Output
The /BK signal will remain ON during overtravel. The brake will remain released.
