A.6 Connecting MITSUBISHI's AD72 Positioning Unit
The following diagram shows an example of connecting to the MITSUBISHI AD72
Positioning Unit. In this example, the servo amplifier is used in Speed Control Mode.
*1. The ALM signal is output for approximately two seconds when the 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. Pin numbers are the same for both the X axis and the Y axis.
*3. Connect the connector wire of the cable to the connector shell.
*. P indicates twisted pair wires
Note Only signals applicable to MITSUBISHI’s AD72 Positioning Unit and Yaskawa’s
SGDM servo amplifier are shown here.
