10.1 Connection to Host Controller

10.1.4 Connection to OMRON’s Position Control Unit
The ALM signal is output for about five seconds after the control power 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.
Set parameter Pn200.0 to "
1."
Connect the shielded wire to the
connector shell.
represents twisted-pair wires.
Note 1. Only the signals related to the SGDV SERVOPACK and the OMRON Position Control Unit are shown in the
diagram.
2. The main circuit power supply is a three-phase 200 VAC SERVOPACK input in the example.
3. Incorrect signal connections will damage the Position Control Unit or SERVOPACK. Wire all connections care-
fully.
4. Open the signal lines not to be used.
5. The above connection diagram shows only X-axis connections. When using other axes, make connections to the
SERVOPACK in the same way.
6. Short-circuit the normally closed (NC) input terminals that are not used at the I/O connector section of the posi-
tion control unit.
7. Make the settings so that the servomotor can be turned ON/OFF by the Servo ON (/S-ON) signal.
8. The SERVOPACK incorporates safety functions to protect people from the hazardous operation of the movable
parts of the machines, reduce the risk, and ensure the safety of the machine in operation. Necessary circuits and
settings are required in CN8 to use these functions. If these functions are not used, use the SERVOPACK with the
enclosed safety jumper connected to CN8. For details, refer to 5.11 Safety Function.
