(3) Brake Signals (/BK) Allocation
The brake signal (/BK) is not allocated at shipment. Use the parameter Pn50F to allocate the /BK signal.

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.
(4) Brake ON Timing after the Servomotor Stops
When the servomotor stops, the /BK signal turns OFF at the same time as the /S_ON signal is turned OFF. The
servomotor power OFF timing can be changed with the parameter Pn506.

• When using the servomotor to control a vertical axis, the
machine movable part may shift slightly depending on
the brake ON timing due to gravity or an external force.
By using this parameter to delay turning the servo OFF,
this slight shift can be eliminated.
• This parameter changes the brake ON timing while the
servomotor is stopped.
The servomotor will turn OFF immediately when an alarm occurs, regardless of the set-
ting of this parameter. The machine movable part may shift due to gravity or external
force during the time until the brake operates.
