Pin No.

36
Signal that indicates that transmission data is ready in the ABS transfer
35
mode.

Common for near-point dog signal, upper/lower limit, stop signal,
34
speed/position changeover signal, and external start signal.

Common for ABS data bit 0, ABS data bit 1 and ABS transmission data
33
READY.

32
Common for servo ON, ABS transfer mode and ABS request.
31 
Signal that requests ABS data during ABS transfer mode.

Used to select the ABS transfer mode.
30

While this signal is ON, the "ABS data bit 0", "ABS data bit 1" and "ABS
send data READY" signals are valid.

Signal that powers on the base circuit of the servo to make it ready to
29
operate.

Input the pulse signal from the manual pulse generator A phase and B
phase.

If the A phase is advanced more than the B phase, the positioning
28
address will increase at the rising edge and falling edge of each phase.
27

If the B phase is advanced more than the A phase, the positioning
address will decrease at the rising edge and falling edge of each phase.

26 
Common for drive unit READY and in-position.

23
Common for deviation counter clear.

25
Common for zero point signal (+5V) and zero point signal (+24V).

Input the zero point signal for machine zero point return.
Use the zero point signal of the pulse encoder or the like.
24 
Use this signal when the zero point return method is the stopper stop
6
method and the machine zero point return complete is input from an
external source.

The zero point signal is detected at turning from OFF to ON.
22
21

Output the positioning pulses and pulse sign for the differential driver
compatible drive unit.
