Product details

1-axis positioning with differential driver output

The QD75D1N is a single-axis positioning unit from Mitsubishi Electric's Melsec Q series, using differential driver pulse output for noise-immune communication with servo drives over cable runs up to 10 m. It outputs up to 4 Mpps, supporting speed commands from 0.01 mm/min to 20000000.00 mm/min and positioning ranges from -214748364.8 to 214748364.7 μm in incremental or absolute mode.

Battery-less parameter backup

Positioning parameters, positioning data, and block start data are saved in flash ROM, eliminating the need for a battery backup — a practical advantage for machines where battery replacement access is difficult or where long-term storage without power is required. The unit occupies 32 points of intelligent I/O in the PLC rack and draws 0.43 A from the 5 V backplane supply.
