(3) Brake ON Timing after the Servomotor Stops
When the servomotor stops, the /BK signals turn OFF at the same time as the Disable operation command is
received. Use Pn506 to change the timing to turn OFF the servomotor power after the Disable operation com-
mand has been received.
•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.
To eliminate this slight shift, set parameter so that the
power to the servomotor turns OFF after the brake is
applied.
•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.
