(2) Brake Signal (/BK) Setting
This output signal controls the brake. The allocation of the /BK signal can be changed. Refer to (3) Brake Sig-
nal (/BK) Allocation for allocation.
The /BK signal turns OFF (applies the brake) when an alarm is detected or the SV_OFF command is received.
The brake OFF timing can be adjusted with Pn506.
(3) Brake Signal (/BK) Allocation
Use parameter Pn50F.2 to allocate the /BK signal.
(4) Brake ON Timing after the Servomotor Stops
When the servomotor stops, the /BK signal turns OFF at the same time as the Servo ON command is turned
OFF. Use parameter Pn506 to change the timing to turn OFF the servomotor power after the Servo ON com-
mand has been turned OFF.

The /BK signal is output from output
terminal CN1-23, 24.

The /BK signal is output from output
terminal CN1-25, 26.
When multiple signals are allocated to the same output terminal, the signals are output
with OR logic. For the /BK signal, do not use the output terminal that is already being
used for another signal.
