[4] When the hardware stroke limit function is not used
When not using the hardware stroke limit function, set the logic of FLS and RLS
to the "negative logic" (initial value) with "[Pr.22] Input signal logic selection" and
input the signal which always turns ON. Otherwise, set the logic of FLS and RLS
to the "positive logic" with "[Pr.22] Input signal logic selection" and always turn
OFF the input.
[5] Servo parameter setting [CiA402 mode]
Set "Sensor input type selection" of the servo parameter "Function selection D-4
(PD41)" properly at MR-J4-GF use. Otherwise, the stroke limit signal cannot be
released. The operation at stroke limit detection according to each setting is as
follows.

1 : The error "Servo parameter PD41 setting error" (error code: 1005) occurs. The cyclic transmission is not
performed.
2 : The stroke limit signal cannot be released.
3 : When "1: Enabled only for HPR mode" is set to "Stroke limit enabling condition selection" of the servo
parameter "Function selection D-4 (PD41)"
POINT
The consistency between "[Pr.80] External input signal selection" and the servo
parameter "Function selection D-4 (PD41)" is checked at the start of connection
with the servo amplifier. At the diagnostic error, the error "Servo parameter PD41
setting error" (error code: 1005) occurs and the cyclic transmission with the servo
amplifier of the target axis is not performed.
