When the limit switch signal is active during motor running, it sets the deceleration mode of the servo
motor from rotation to stop and the servo motor status .
Value Stop Mode
0 Coast to stop, keeping the de-energized state
1 DB stop, de-energized state
2 DB stop, keeping the DB state
In the vertical axis application, set 2002-08h = 1 to make the motor axis in position locking state after the
limit switch signal is active to ensure safety.
After the brake output is enabled, the stop mode at limit switch signal option is changed forcibly to “Stop at
zero speed, position remains locked."
To prevent the workpiece from falling when the limit switch signal is active in the vertical axis
application, set 2002-08h to 1. When the workpiece moves in a linear manner, make sure to
connect the limit switch to prevent mechanical damages. If the limit switch signal becomes
active, enter a reverse reference to make the motor (workpiece) run in the reverse direction.
Figure 6-2 Limit switch installation
To use the limit switch function, set two DI terminals of the servo drive respectively with
function 14 (FunIN.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.

limit switch
When the mechanical movement is out of range, the
servo drive implements the function of preventing the
motor from sensing the limit switch.

limit switch
When the mechanical movement is out of range, the
servo drive implements the function of preventing the
motor from sensing the limit switch.
