•
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.

Common 26
•
Common for drive unit READY and in-position.
Deviation counter clear common 23
•
Common for deviation counter clear.
Zero point signal common 25
•
Common for zero point signal (+5V) and zero point signal (+24V).
Zero point signal (+5V)
Zero point signal (+24V) 24
6
•
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 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.

•
Output the positioning pulses and pulse sign for the open collector
compatible drive unit.
External start signal 16
•
Use as the positioning start, speed change request and skip request
input signal from an external source.
•
Set which function to use the external start signal with in " Pr.43
External start function selection".
Speed/position changeover signal 15
•
Input the control changeover signal for the speed/position changeover
control.
Stop signal 14
•
Input when positioning is stopped.
•
When this signal turns ON, the AD75 will stop the positioning being
executed.
After that, even if this signal turns from ON for OFF, the system will not
start.
