11.2.10 Example of Connection to MITSUBISHI’s AD75 Positioning Unit
(SERVOPACK in Position Control Mode)
* The ALM signal is output for about 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 the main circuit power supply to the SERVOPACK.
Note: Only signals applicable to Mitsubishi’s AD75 Positioning Unit and Yaskawa’s SGDH SERVO-
PACK are shown in the diagram.
