2) Contact Output Signal Terminal Connections
These output signals are used
to indicate DR2 Servopack
operation status.
Photocoupler output
Per output
Maximum operational
voltage: 30 VDC
Maximum output
current: 50 mA DC
Open collector output
Per output
Maximum operational
voltage: 30 VDC
Maximum output
current: 20 mA DC
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.
Output → SG
This signal ground is used for the following output signals. Connect to 0 V on the external
power supply.
