g Example
The following wiring example shows the wiring when an OMRON G5-series Servo Drive and Servomo-
tor (R88D-KT

or R88M-K

) are used.
The external output 0 (O0) from the NX-PG0122 Pulse Output Unit is a PNP output. In this example, it
is used as an error counter reset output.
To connect to the following error counter reset input (ECRST) of the Servo Drive, connect to the input
common (+24 VIN) of the Servo Drive to the IOG (I/O power GND) of the NX Unit. The Servo Drive sup-
ports both PNP and NPN inputs.
Also connect the operation command input (RUN) and error reset input (RESET) (which have the same
common) to a PNP Output Unit.
When connected in the same Slave Terminal, the I/O power supply is shared by the entire Slave Termi-
nal if an Additional I/O Power Supply is not used.
Wiring errors or mixing PNP and NPN outputs may cause damages or malfunctions.
