(SERVOPACK in Position Control Mode)
* The ALM signal is output for about 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 the main circuit power supply to the SERVOPACK.
Note: Only signals applicable to Mitsubishi’s AD75 Positioning Unit and Yaskawa’s SGDJ-†††P
SERVOPACK are shown in the diagram.
