The ALM signal is output for approximately two seconds when the power is turned ON. Take this into consider
ation when designing the power ON sequence. The ALM signal actuates the alarm detection relay 1Ry to stop
main circuit power supply to the Servopack.
* .
Connect the shield wire of the I/O cable to the connector shell.

P indicates twistedpair wires.
Note Only signals applicable to OMRON's C500NC221 Position Control Unit and Yaskawa's SGDM Servopack
are shown here.
