The Mitsubishi QD75D4N is a 4-axis positioning module for the MELSEC Q Series, using differential driver output for noise-resistant pulse trains up to 1 Mbps. It controls speed using pulse-train output and supports linear interpolation on 2 to 4 axes, circular interpolation on 2 axes, and helical interpolation on 3 axes — enough coordinated motion for pick-and-place, gantry, or rotary stations without an external motion controller. Per-axis storage holds 600 positioning data points, and a built-in parameter-backup feature retains that data across power cycles, so you avoid re-teaching after a line restart. Maximum cable length between the module and each servo drive is 10 m, which suits typical panel-to-machine reach without a repeater.
For a BOM line specifying a Q-series 4-axis differential-output positioning module, this is the exact fit. Source via RFQ; no substitute is required.
