15.1.4 Example of Connections to an OMRON Position Control
Unit
*1. The ALM (Servo Alarm) signal is output for approximately five seconds when the power supply is turned ON.
Take this into consideration when designing the power ON sequence. Also, use the ALM signal to actuate the
alarm detection relay (1Ry) to stop the main circuit power supply to the SERVOPACK.
*2. Set Pn200 to n.1 (CW and CCW pulse trains with positive logic).
*3. Connect the shielded wire to the connector shell.
*4. represents a shielded twisted-pair cable.
Note: 1. Only the signals that are applicable to the SERVOPACK and the OMRON Position Control Unit are shown
in the diagram.
2. The main circuit power supply for the SERVOPACK in this connection example is three-phase 200 VAC.
3. Incorrect wiring may damage the Position Control Unit or SERVOPACK. Wire all connections carefully.
4. Do not wire any unused signal lines (i.e., leave them open).
5. The above wiring diagram shows the connections for only the X axis. If you will use other axes, make con-
nections to the SERVOPACK in the same way.
6. All normally closed input terminals that are not used at the Position Control Unit’s I/O connector section
must be connected at the connector.
7. Set the parameters so that the servo can be turned ON and OFF with the /S-ON (Servo ON) signal.
8. The SERVOPACK provides safety functions to protect people from the hazardous operation of the moving
parts of the machine. In order to use the safety functions, the required circuits must be configured for CN8.
If the safety functions will not be used, leave the enclosed Safety Jumper Connector connected to the
SERVOPACK (CN8). Refer to the following chapter for details.
