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 SIN18-40 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Travel and resolution
- Step/half-step resolution(°): ≈0.0179/0.009 · Resolution under 20 subdivision(°): ≈0.0009
- 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 28 steeping，1.8 · Brand and model number of motor: Shinano，STP-28D1003-08
- 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.
