Note Provide an external I/O power supply separately.
There are no power terminals to which the DR2 Servopack outputs signals exter-
nally.
Yaskawa recommends that this external power supply be the same type as for the
input circuit.

This signal ground is used for the following output signals. Connect to 0 V on the external
power supply.
