It sets the deceleration mode of the servo motor from rotation to stop and the servo motor status when the limit
switch signal is active during motor running.
Value Stop Mode
0 Coast to stop, keeping the de-energized state
1 Stop at zero speed, position remains locked
2 Stop at zero speed, keeping de-energized state
In the vertical axis application, set 2002-08h = 1 to fix the motor axis in the position locking state after the limit switch
signal is active to ensure safety.
After enabling the brake output, stop mode at limit switch signal option is forced to "Stop at zero speed, position
remains locked."
When the limit switch signal is active in the servo motor’s vertical axis application, the workpiece might fall.
To prevent the workpiece from falling when the limit switch signal is active, set (2002-08h) to "1-Stop at zero
speed, the position remains locked." When the work moves in linear, make sure to connect the limit switch to
prevent mechanical damage. If the limit switch signal becomes active, enter a reverse reference to make the
motor (workpiece) run in reverse direction.

To use the limit switch function, set two DI terminals of the servo drive respectively with function 14 (Fu-
nIN.14: P-OT, positive limit switch) and function 15 (FunIN.15: N-OT, negative limit switch) to receive the
limit switch input level signals, and set the terminal logics. The servo drive determines whether to enable or
disable the limit switch function based on the DI terminal level.
