3.4.4 Interface internal circuit
The outline diagrams of the internal circuits for the external device connection interface
(for the Simple Motion module, axis 1) are shown below.
(1) Interface between external input signals/forced stop input signals
(Note-1): When using external input signal of servo amplifier, set "1" with " External signal selection". In addition,
refer to Section 13.4.4 for wiring of upper/lower limit signal and Section 8.1.1 for wiring of near-point dog signal.
(Note-2): "_ _" indicates "1A (AX1)", "1B (AX2)", 2A (AX3)", or "2B (AX4)".
(Note-3): As for the 24VDC sign, both "+" and "-" are possible.
