■When "2: Buffer memory" is set to the input type
Use the control data shown below to operate the external input signals (upper/lower stroke limit signal, proximity dog signal,
and stop signal).

Refer to the following for the setting details.

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), proximity
dog signal (DOG), stop signal (STOP), and external command signal/switching signal (DI)) of the servo amplifier or external
device connected with the 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.
The logic setting method for external input signals (upper/lower limit signal, proximity dog signal and stop signal) is shown
below.
Input type of "[Pr.116] FLS signal selection"
to "[Pr.119] STOP signal selection"
1: Servo amplifier
2: Buffer memory
■Parameter setting
Use the following parameter to switch the logic of the external input signals from the servo amplifier and buffer memory
(upper/lower stroke limit signal (FLS/RLS), proximity dog signal (DOG), stop signal (STOP), and external command/switching
signal (DOG)).
Setting item
[Pr.22] Input signal logic selection
Refer to the following for the setting details.
Page 422 Detailed parameters 1
When the external input signal of the servo amplifier is used, set the same value as the value set in the input logic setting of
the servo amplifier. If the value is not same as the value of the input logic setting, the limit signal may be detected during the
home position return. For the input logic specification of the servo amplifier, refer to the instruction manual of the servo
amplifier to be used.
