Stroke end

Select a servo motor stop method for when the stroke end is off with the first digit setting of [Pr. PD12].
[Pr. PD12]
Stop method selection at stroke limit detection
1: Slow stop
2: Slow stop (deceleration to a stop by deceleration time constant)
3: Quick stop (stop by clearing remaining distance)
In "Sensor input type selection" of [Pr. PD41], the use of limit switches changes as follows.
[Pr. PD41] = "0 _ _ _": The stroke end (LSP and LSN) of the amplifier input is used.
[Pr. PD41] = "1 _ _ _": The controller input stroke limit (RY (n + 1) 0/RY (n + 1) 1) is used.

Remark
The droop pulses are
erased and the servo
motor stops.
The home position is
erased.
There is a difference
between the command
and current positions.
Perform a home position
return again.
Travels for the droop
pulse portion and stops
the servo motor.
Maintains the home
position. However, a
difference will be
generated between the
command position and
the current position.
Perform a home position
return again.
Decelerates to a stop
with the deceleration
time constant currently
selected with the point
table.
Continues operation for
a delay portion of the S-
pattern acceleration/
deceleration time
constants. The home
position is maintained.
A difference will not be
generated between the
command position and
the current position.
