Features:
- Four controlled axes support independent moves and coordinated interpolation.
- Each axis stores as many as 600 positioning records with selectable engineering units.
- SSCNET communication works with separate external limit, stop, changeover, and pulse-signal connections.
QD75M4 divides the front connector into four machine-signal groups that correspond to the controlled axes.
Positioning records on QD75M4 combine target, speed, acceleration, and path information for execution.
The MELSEC-Q backplane and SSCNET link give QD75M4 separate controller and servo communication paths.
The Mitsubishi Electric QD75M4 MELSEC-Q Four-Axis Positioning Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Four-Axis Motion Organization
- Independent moves: Each axis can execute its own positioning record.
- Linear paths: Two, three, or four axes can share one linear interpolation command.
- Circular paths: Two selected axes form a circular interpolation pair.
- Units: Each configured axis uses the selected linear, angular, or pulse unit.
Servo Communication Path
- Network role: SSCNET transfers positioning commands and servo feedback.
- Axis mapping: Each connected amplifier is assigned to the corresponding module axis.
- Startup match: Module parameters and servo-system settings must describe the same axis order.
- Fault boundary: Network and amplifier diagnostics distinguish a servo-path fault from an external input state.
External Machine-Signal Chain
- Limits: Upper and lower limit inputs define the permitted travel boundary.
- Near point: The DOG signal identifies the approach region used by the positioning sequence.
- Stop and change: STOP and CHG inputs apply their configured external-command functions.
- Manual pulse: A- and B-phase inputs accept the supported manual pulse generator signals.
Record and Connector Preparation
- Position data: Target, speed, acceleration, and path method are set in each record.
- Connector choice: A6CON connector variants determine the permitted wire size and termination.
- Axis labels: The two front connector groups separate axes 1/2 from axes 3/4.
- Temperature: The installed module remains within the documented 0 to 55 °C operating range.
