Installation Guidelines
Mounting Requirements
- Install on a flat and stable surface
- Avoid uneven mounting to prevent angle deviation
Axis Alignment (Critical)
- X-axis → Forward direction
- Y-axis → Lateral direction
- Z-axis → Upward direction
👉 Incorrect alignment will lead to wrong data output
Correct Installation
✔ Flat mounting surface
✔ Proper axis orientation
Incorrect Installation
✖ Uneven surface
✖ Misaligned axes
Startup Condition
- Keep device static for first 0.5 seconds
- Ensures accurate initial calibration
Cable & Vibration Tips
- Avoid cable tension or twisting
- Ensure firm mounting even in vibration environments
Applications
- Agricultural autonomous machinery
- AGV / AMR robots
- Unmanned ground vehicles (UGV)
- Industrial automation systems
- Navigation and motion control
