[1] Control details
(1) External input signal of servo amplifier
For the operation when the servo amplifier stroke limit is detected, confirm the specifications of the
servo amplifier to be used. The following shows the case of MR-J4-GF use.

1: Set the following servo parameters properly. (Refer to "[5] Servo parameter setting" for details.)

Set "0: Input from servo amplifier" to "Sensor input type selection" of the servo parameter "Function
selection D-4 (PD41)".

Set "1: Enabled only for home position return mode" to "Stroke limit enabling condition selection" of the
servo parameter "Function selection D-4 (PD41)".

Assign the LSP/LSN signal with the servo parameter "Input device selection 1 to 3 (PD03 to 05)".
2: The signal to be wired differs by the servo parameter "Rotation direction selection/travel direction selection
(PA14)".
Setting value of "Rotation direction selection/travel direction selection
0: Forward rotation (CCW) with the increase of the positioning address
1: Reverse rotation (CW) with the increase of the positioning address
3: Set the same value in "[Pr.22] Input signal logic selection" as the value set in the input logic setting of the
servo amplifier. For the input logic specification of the servo amplifier, refer to the instruction manual of the
servo amplifier to be used.
4: The Simple Motion module executes the stop process.
(2) External input signal via CPU (buffer memory of QD77GF)
