(SERVOPACK in Speed Control Mode)
* 1. The ALM signal is output for approximately two seconds when the control 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 I/O cable’s shield wire to the connector shell.
* 3.
represents twisted-pair wires.
Note: Only signals applicable to OMRON’s C500-NC221 position control unit and Yaskawa’s SGDJ-
S SERVOPACK are shown in the diagram.
