Product details

1-axis positioning with open collector output

The QD75P1N is a single-axis positioning module for Mitsubishi PLC systems, outputting pulse trains via open collector outputs at up to 200 kpps. It occupies 32 I/O points as an intelligent module, drawing 0.29 A from the 5 V backplane. Control methods include PTP (point-to-point), linear/circular/helical trajectory, speed control, and position/speed switching — all selectable per positioning data block. Acceleration/deceleration uses trapezoidal or S-curve profiles with independent accel/decel times per pattern.

Positioning range and data storage

Positioning data is stored in flash ROM with no battery required — parameters, positioning data, and block start data survive power loss without a backup battery. The module supports 600 positioning data points per axis. Command units can be set to mm, inch, degree, or pulse. The absolute positioning range spans ±214748364.8 μm, ±21474.83648 inch, 0 to 359.99999 degree, or ±2147483648 pulses. Incremental positioning covers the same range.

Wiring and physical fit

External wiring connects through a 40-pin connector (mates with A6CON1, A6CON2, or A6CON4, sold separately). Maximum cable distance between the module and servo drive is 2 m. The module measures 27.4 mm wide, 98 mm high, and 90 mm deep.

Frequently asked questions

What is the maximum pulse output frequency of the QD75P1N?

The maximum output pulse frequency is 200 kpps (200,000 pulses per second) via the open collector output. This limits the achievable motor speed based on the encoder resolution and servo amplifier input frequency.

Does the QD75P1N require a battery to retain positioning data?

No. The QD75P1N stores parameters, positioning data, and block start data in flash ROM — battery-less backup. No battery is needed for data retention during power-off.

What connector does the QD75P1N use, and what is the cable length limit?

The module uses a 40-pin connector compatible with Mitsubishi A6CON1, A6CON2, or A6CON4 (sold separately). The maximum cable distance between the module and the servo drive is 2 m.
