A.4 Connecting OMRON's C500-NC221 Position Control Unit
The following diagram shows an example of connecting to an OMRON C500-NC221
Position Control Unit. In this example, the servo amplifier is used in Speed Control
Mode.
*1. The ALM signal is output for approximately two seconds when the power is turned
ON. Take this into consideration when designing the power ON sequence. The ALM
signal actuates the alarm detection relay 1Ry to stop main circuit power supply to the
servopack.
*2. Connect the shield wire to the connector shell.
*. P indicates twisted pair wires.
Note Only signals applicable to OMRON’s C500NC221 Position Control Unit and
Yaskawa’s SGDM servo amplifier are shown here.
