- 12. Install the remaining magnet tracks in the order shown.
- 13. Slightly loosen the mounting screws on the exposed magnet tracks.
- 14. Align the magnet tracks with an aluminum straight edge, and the supplied alignment tool.
- 15. Place the alignment tool in the holes on each of the magnet tracks.
- 16. Align the edges of the magnet tracks with the aluminum straight edge and tighten the bolts.
- 17. Position the carriage over the complete sections and continue aligning the remainder of the magnet tracks.
- 18. Torque all screws to the values listed in the table, securing assemblies in place by using all mounting holes.
- Mount a Single Coil with a Single Magnet Track
- 1. Install the magnet track by using M5 x 0.8 x 16 mm SHCS.
- 2. Remove any burrs and clean the motor-coil mounting surface.
- 3. Install the motor coil under the carriage, by using M5 x 0.8 screws that extend through the carriage by at least 12 mm (0.5 in.), but no more than 20 mm (0.7 in.).
- 4. Tighten screws but do not torque them.
- 5. Slide the carriage assembly onto the bearing pucks.
- 6. Attach the carriage assembly to the bearing pucks.
- 7. Measure the gap between the motor and magnet by using plastic shim stock.
- 8. Torque all screws to the values listed in the table, securing assemblies in place by using all mounting holes.
