(2) Brake Signal (/BK) Setting
This output signal controls the brake. The output signal must be allocated with Pn50F. 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 /S-ON signal is turned OFF.
The brake OFF timing can be adjusted with Pn506.

n. 1 CN1-7
The /BK signal is output from output termi-
nal CN1-7.
n. 2 CN1-9
The /BK signal is output from output termi-
nal CN1-9.
n. 3 CN1-10
The /BK signal is output from output termi-
nal CN1-10.
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.
