8 Pulse Output Units

NX-series Position Interface Units User’s Manual (W524)
Precautions for Correct Use
• The external output 0 (O0) from the NX-PG0112 Pulse Output Unit is an NPN output. In this
example, it is used as a following error 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 IOV (I/O power 24 V) of the NX Unit.
The Servo Drive supports both PNP and NPN inputs.
• If you use the phase-Z input signal, connect it to external input 0 on the Pulse Output Unit.
Also, set the External Input 0 Function Selection parameter to Latch Input 1. Refer to
External Input Function Selection
on page 8-65 for information on external input signals.
• Also connect the operation command input (RUN) and error reset input (RESET) (which
have the same common) to an NPN Output Unit.
• If all of the Units are mounted to the same Slave Terminal and an Additional I/O Power Sup-
ply Unit is not used, the I/O power supply is shared by the entire Slave Terminal.
• Wiring mistakes or mixing PNP and NPN outputs may cause damage or malfunctions.
• The above example shows only the major signals that are required to control the Servo
Drive. You need to add operation commands for errors, cutoff circuits for the main power sup-
ply, and any other circuits that are required for safety.
This section provides diagrams of the terminal block arrangement and internal power supply wiring of
the NX-PG0122. It also provides a wiring example.
A 16-terminal terminal block is used.
Note The sensor power supply output (24 V and 0 V) is provided power from the I/O power supply connected to
the Communications Coupler Unit or an Additional I/O Power Supply Unit.
