10.1.3 Connection to OMRON’s Motion Control Unit
10-4
10.1.3 Connection to OMRON’s Motion Control Unit
represents twisted-pair wires.
This connection is to adjust the p
hase of the encoder output pulse.
Note 1. Only the signals that are related to the SGDV SER
VOPACK and the OMRON Motion 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 cause damage to the motion control unit and SERVOPACK. Wire all connec-
tions carefully.
4. Open the signal lines not to be used.
5. The above connection diagram shows the connections for only one axis. When using other axes, make connec-
tions 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 motion
control unit.
7. Make the settings so that the servomotor can be turned ON/OFF by the Servo ON signal (/S-ON).
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.
