(3) Brake Signals (/BK) Allocation
Use the parameter Pn50F.2 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 Linear Servomotor Stops
When the linear servomotor stops, the /BK signal turns OFF at the same time as the servo ON command is
turned OFF. The Pn506 parameter can be used to change the timing at which the servo ON command turns
OFF and power is not supplied to the linear servomotor.

• When using the linear 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 turn the servo OFF after the brake is
applied, the slight shift can be eliminated.
• This parameter changes the brake ON timing while the linear
servomotor is stopped.
The linear servomotor will turn OFF immediately when an alarm occurs, regardless of
the setting of this parameter. The machine movable part may shift due to gravity or exter-
nal force during the time until the brake operates.
