35
Signal that indicates that transmission data is ready in the ABS transfer
mode.
ABS transmission data READY
34
Common for near-point dog signal, upper/lower limit, stop signal,
speed/position changeover signal, and external start signal.
Common (ABS IN)
33
Common for ABS data bit 0, ABS data bit 1 and ABS transmission data
READY.
Common (ABS OUT)
32
Common for servo ON, ABS transfer mode and ABS request.
ABS request
31
Signal that requests ABS data during ABS transfer mode.
ABS transfer mode
30
Used to select the ABS transfer mode.
While this signal is ON, the "ABS data bit 0", "ABS data bit 1" and "ABS
send data READY" signals are valid.
Servo ON
29
Signal that powers on the base circuit of the servo to make it ready to
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
address will increase at the rising edge and falling edge of each phase.
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.

Input the zero point signal for machine zero point return.
Use the zero point signal of the pulse encoder or the like.
Use this signal when the zero point return method is the stopper stop
method and the machine zero point return complete is input from an
external source.
