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 When using external input signal of servo amplifier, set "1" with "[Pr.116] FLS signal selection", "[Pr.117] RLS signal selection", and
"[Pr.118] DOG signal selection".
*2 Refer each servo amplifier instruction manual for wiring of the input/output signals of servo amplifier.
*3 "_ _" indicates "1A", "1B", 2A ", or "2B".
*4 As for the 24 V DC sign, both "+" and "-" are possible.

*1 Set "0: Differential-output type" in "[Pr.89] Manual pulse generator/Incremental synchronous encoder input type selection" if the manual
pulse generator/Incremental synchronous encoder of differential-output type is used.
The default value is "1: Voltage-output/open-collector type".
*2 Set the signal input form in "[Pr.24] Manual pulse generator/Incremental synchronous encoder input selection".
*3 The 5 V DC power supply from the Simple Motion module must not be used if a separate power supply is applied to the manual pulse
generator/incremental synchronous encoder. If a separate power supply is used, use a stabilized power supply of voltage 5 V DC.
Anything else may cause a failure.
