(5) Brake Signal (/BK) Output Timing during Servomotor Rotation
If an alarm occurs while the servomotor is rotating, the servomotor will come to a stop and the brake signal
(/BK) will be turned OFF. The timing of brake signal (/BK) output can be adjusted by setting the brake refer-
ence output speed level (Pn507) and the waiting time for brake signal when motor running (Pn508).
Note: If the servomotor is set so that it comes to a zero-speed stop for an alarm, follow the information in

/BK Signal Output Conditions
When Servomotor Rotating
The /BK signal goes to high level
(brake ON) when either of the fol-
lowing conditions is satisfied:
• When the motor speed falls
below the level set in Pn507
after the power to the servomo-
tor is turned OFF.
• When the time set in Pn508 is
exceeded after the power to the
servomotor is turned OFF.

• The servomotor will be limited to its maximum speed even if the value set in Pn507 is
higher than the maximum speed.
• Do not allocate the rotation detection signal (/TGON) and the brake signal (/BK) to the
same terminal. The /TGON signal will otherwise be turned ON by the falling speed on
a vertical axis, and the brake may not operate.
For the /BK signal, do not use the terminal that is already being used for another
signal.
