The Mitsubishi FX5-20PG-P is a current-production 2-axis pulse train positioning module that handles the motion logic so the FX5 CPU stays free for other duties. It runs on 24 V DC and draws 120 mA from the backplane.
Control modes and interpolation
Supports PTP (point-to-point), path control with linear and circular arcs, speed control, and speed-position switching. It interpolates across 2 axes — both linear and circular. Positioning data is stored at 600 data points per axis in battery-free flash ROM, so no periodic battery swaps.
Power and compatibility
Operates on 24 V DC (+20%, -15%) and tolerates instantaneous power breaks shorter than 5 ms without dropping motion. The module plugs into the FX5 expansion bus and requires a compatible FX5 CPU (e.g., FX5U or FX5UC) — it is not a standalone controller.
