STS40 floor-mount on the PacDrive 3 line
The LXMSTS40F400000 is the STS40 SCARA robot in the Schneider Electric PacDrive 3 line, configured as a floor-mount unit with a 400-class ball-screw drive and the user I/O cable option. It carries the US1PC5218357 category designation under the Servo Drives catalog path and ships as a single unit per package. For a controls integrator selecting a robot on this platform, the short name 'STS40' and the ball-screw 400 form-factor identify the unit when matching it against existing PacDrive 3 cells.
Kinematics: four axes at production-grade repeat
Four axes of motion with ±0.01 mm repeat accuracy define this unit's fit for pick-and-place and small-parts assembly cells where positional consistency drives yield. Rotational operation covers a full 360° envelope, with an operating travel envelope of 0…800 mm horizontal and 0…400 mm vertical on the linear axes. For an integrator matching this to a workstation layout, the horizontal/vertical travel budget is the first constraint checked against the cell footprint.
Speed ratings — nominal, maximum, and actuation ceiling
Nominal axis speeds run 450°/s (axis 1) and 600°/s (axis 2) angular, with a linear axis 3 at 2000 mm/s, while the axes 1 and 2 linear equivalents reach 4.92 m/s nominal — the maximum actuation ceiling stretches to 2220 mm/s on axis 3 and 6.91 m/s on axes 1 and 2. Axis 4 is rated 1200°/s nominal and 1929°/s maximum angular, which is the figure that matters when a tooling end-effector needs to clear a conveyor handoff within the cycle budget.
Lifecycle status and how to source it
For a buyer with an installed base, that translates into locking down spares now while known-good stock still moves, because once the broker pool drains there is no factory source to fall back on.
