STS80 SCARA — what this order code actually specifies
The LXMSTS80F400000 is a Schneider Electric STS80 SCARA robot in the PacDrive 3 family, a 4-axis floor-mount machine on a ball-screw 400 vertical stroke with a user I/O cable variant, designed for normal-environment assembly and pick-and-place cells rather than washdown or cleanroom duty.
Axis speeds and operating envelope
Axis 4 tops out at 1929°/s with a 1200°/s nominal rate, while the planar axes run 500°/s nominal and 585°/s maximum on axis 2 and 350°/s nominal / 490°/s maximum on axis 1 — the asymmetric profile reflects the heavier inertial work handled by axis 1 (the shoulder) versus the lighter tool-side axis 4. Linear speeds translate those rotary figures into 8.11 m/s nominal on axes 1 and 2 with a 10.62 m/s maximum actuation rate, and the vertical (axis 3) operates at 1600 mm/s nominal up to 2220 mm/s, bounded by the ball-screw 400 stroke envelope of 0 to 400 mm vertical and 0 to 1600 mm horizontal. Cycle-time budgeting on this arm should treat the axis-3 maximum (2220 mm/s) and the axis-1/axis-2 maxima (10.62 m/s) as separate ceilings rather than one combined top speed — a long horizontal traverse capped at the vertical axis rate is a common under-spec on this class.
Sourcing posture for an obsolete SCARA arm
For an integrator sizing a new line today, the obsolete status makes this arm a sustainment choice only — a new build on PacDrive 3 should pick from the active STS variants rather than committing to a discontinued order code.
