Application context
Why this design is used
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Repeatable production indexing
Move parts between fixed stations with closed-loop encoders holding position over long shifts.
Programmable multi-axis motion
Coordinate several axes from software for processing, inspection and test sequences.
System integration
Integration and compatibility
Use these checks to connect PSAV50-240ZF to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Travel and resolution
- Travel range(mm): 50 · Resolution (step/half-step) (µm): 6.25/3.125
- Separate travel from resolution and both from repeatability. Repeatability is what an automated sequence actually depends on, and it is the figure most often absent from a headline specification.
- Drive and feedback
- Motor and its stepping angle (°): Two-phase 57 stepping motor, 1.8 · Model number of motor**: MS-57BYG250CSC
- Pair open-loop mechanics with the specified high-voltage or inertial driver, and closed-loop variants with the controller their capacitive, strain-gauge or encoder feedback requires. Matching connectors do not guarantee electrical compatibility.
- Load and mounting
- Horizontal load(Kg)***: 200
- Check the load rating in the orientation you will use it — a vertical or cantilevered load is a moment, not a mass — and match the base to an M6 pattern on a 25 mm grid or a 1/4"-20 pattern on a 1 inch grid.
