* 1. The ALM signal is output for about two seconds after the power is turned ON. Take this into consid-
eration 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.
* 2. Pin numbers are the same both for X-axis and Y-axis.
* 3. Connect the connector wire to the connector shell.
* 4. represents twisted-pair wires.
Note: Only signals applicable to Mitsubishi’s AD72 Positioning Unit and Yaskawa’s SGDH SERVO-
