* 1. The ALM signal is output for about two seconds after 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.
* 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 SGDJ-†††S
