11.1.5 Connection to MITSUBISHI’s AD72 Positioning Module
(SERVOPACK in Speed Control)
∗1. The ALM signal is output for about five seconds after the control power is turned ON. Take this into consideration
when designing the power ON sequence. Also, use the ALM signal to actuate the alarm detection relay 1Ry to stop
the main circuit power supply to the SERVOPACK and converter.
∗2. Pin numbers are the same both for X axis and Y axis.
∗3. Connect the shielded wire to the connector shell.
∗4. represents twisted-pair wires.
∗5. This connection is to adjust the phase of the encoder pulse output.
Note 1. Only signals related to the SERVOPACK and the AD72 Mitsubishi Positioning Module are shown in the dia-
gram.
2. The main circuit power supply is a three-phase 200-VAC SERVOPACK and converter input in the example.
3. Incorrect wiring may damage the Positioning Module, SERVOPACK, or converter. Wire all connections care-
fully.
4. Open the signal lines not to be used.
5. The above connection diagram shows the connections for only one axis. When using other axes, make connec-
tions to the SERVOPACK in the same way.
6. Short-circuit the normally closed (NC) input terminals that are not used at the I/O connector section of the posi-
tioning module.
7. Make the settings so that the servo can be turned ON/OFF by the Servo ON (/S-ON) signal.
8. The SERVOPACK incorporates safety functions to protect people from the hazardous operation of the movable
parts of the machines, reduce the risk, and ensure the safety of the machine in operation. Necessary circuits and
settings are required in CN8 to use these functions. If these functions are not used, use the SERVOPACK with the
enclosed safety jumper connected to CN8. For details, refer to 5.11 Safety Function.
