11.1 Connection to Host Controller
11-7
11.1.6 Connection to MITSUBISHI’s AD75 Positioning Module
(SERVOPACK in Position Control)
∗ The ALM signal is output for about five seconds when 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.
Note 1. Only the signals related to the SERVOPACK and the AD75 Mitsubishi Positioning Module are shown in the dia-
gram.
2. The main circuit power supply is a three-phase 200-VAC SERVOPACK input in the example.
3. Incorrect signal connections will damage to the Positioning Module, SERVOPACK, or converter. Wire all con-
nections carefully.
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 servomotor 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.
