5.12.2 /BK (Brake) Signal

5.12.2 /BK (Brake) 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) 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).

If you allocate more than one signal to the same output connector pin, a logical OR of the signals
is output. Allocate the /BK signal to its own output connector pin, i.e., do not use the same out-
put terminal for another signal.
For example, never allocate the /TGON (Rotation Detection) signal and /BK signal to the same
output connector pin. If you did so, the /TGON signal would be turned ON by the falling speed on
a vertical axis, and the brake would not operate.
