Set the input terminal and buffer memory number to be used for each setting value of the "external signal selection" such as
"[Pr.116] FLS signal selection", "[Pr.117] RLS signal selection", "[Pr.118] DOG signal selection" and "[Pr.119] STOP signal
selection".
■When "0: Simple Motion module" is set
The pin number to be used is set as the setting details (input terminal) of "[Pr.116] FLS signal selection", "[Pr.117] RLS signal
selection", "[Pr.118] DOG signal selection", and "[Pr.119] STOP signal selection".
■When "1: Servo amplifier" is set
The following table shows the pin number of the external input signal of the servo amplifier to be used.
(Note): When setting at MR-JE-B use, any errors or warnings do not occur. However, the external input signal (upper/lower
limit signal, near-point dog signal) cannot be operated.

*1 This servo amplifier means about MR-J4_B/MR-JE-_B. Refer to the "Servo Amplifier Instruction Manual" for details on the pin numbers
of MR-J4W_-_B.
*2 The stop signal cannot be input from the external input signal of the servo amplifier.
■When "2: Buffer memory" is set
Uses the control data shown below to operate the external input signals (upper/lower stroke limit signal, near-point dog signal,
and stop signal).

Page 504 Control Data
Input logic setting method for external input signals
The signal logic can be switched according to the external input signals (upper/lower stroke limit signal (FLS/RLS), near-point
dog signal (DOG), stop signal (STOP), and external command signal/switching signal (DI)) of the servo amplifier or external
device connected with the Simple Motion module.
For the system that does not use the upper/lower limit signal with b-contact, this function enables the control without wiring by
setting "Positive logic" to the parameter logic setting.
When using the upper/lower limit signal, be sure to use in the negative logic (b-contact).
For the interface of the logic selection, the setting area varies depending on the input type and signal type of the external
signal.
