An obsolete 4-axis SCARA, not a servo drive
The LXMSTS60W400000: The catalog places this part in Servo Drives as part of the broader PacDrive 3 motion ecosystem, even though the STS60 itself is the mechanical arm that PacDrive 3 controllers and Lexium drives move.
Performance envelope that decides cycle time
Repeatability is +/- 0.01 mm, which is the figure that gates any high-precision assembly, dispensing, or screw-driving application the arm gets specced into. Nominal linear speeds reach 6.39 m/s on axes 1 and 2 and 2000 mm/s on axis 3, with a maximum actuation speed of 8.01 m/s on axes 1 and 2 — the upper bound is what sets the ceiling on horizontal pick-rate, not the nominal figure. Axis 4 carries the slowest ratings in the arm — 1200°/s nominal and 1929°/s maximum angular speed — and that cap is the one that drives end-effector rotation cycle time.
Lifecycle: obsolete, no successor on record
For a line already running the STS60, the path forward is independent-distribution surplus stock rather than the factory channel: lot-specific quantities, quoted to order against the BOM, with current availability and pricing confirmed at RFQ.
