A.7 Connecting MITSUBISHI's AD75 Positioning Unit
The following diagram shows an example of connecting to the MITSUBISHI AD75
Positioning Unit. In this example, the servo amplifier is used in Position 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.
Note Only signals applicable to MITSUBISHI’s AD75 Positioning Unit and Yaskawa’s
SGDM servo amplifier are shown here.
