(2) Wiring for external device connection
The existing AD70/A1SD70 external device connection connectors can be used, so there is no need to
change the wiring.
However, the connector orientation will be reversed when replacing the A1SD70.
The existing AD70/A1SD70 required an external 15 V DC ± current power supply, but the QD73A1 does not
need an external power supply.

The feedback pulse train from the pulse generator (PLG) can pass
through the drive unit (as shown with *1), or directly output to QD73A1
(as shown with *2). The route depends on the servo motor being used.
Refer to the manual for the servo motor and drive module being used
for information on selecting method *1 or *2.
