R-Theta stage movement programs are higher suited to round, elliptic and spiral movement patterns than standard Cartesian 2-axis XY linear translation levels.

PI Gives Three Lessons of R-Theta Phases.
- For the best efficiency and precision, Air Bearing linear levels and air bearing rotary tables are used.
- Hybrid R-Theta programs use linear motor pushed levels with mechanical bearings and direct-drive air bearing rotary tables.
- Direct Drive linear motor levels and direct drive rotary tables with mechanical bearings are additionally out there.
R-Theta programs typically discover functions in precision laser / semiconductor functions as a consequence of larger throughput, larger precision and smaller footprint. Watch video of an all air bearing R-Theta levels.
Excessive Pace Movement Controllers
The levels are operated by PI’s ACS-based industrial movement controllers with ultra-fast triggers for synchronization with exterior tools corresponding to cameras, sensors or lasers. The quick controllers enable extremely exact triggering with 0.01% time tolerance between alerts. Set off alerts may be derived off absolute encoders or analog alerts (sin/cos encoder), enabling larger precision, safer, and simplified options as in comparison with outdated digital encoder-only triggers. With the fashionable PI movement controllers, a set off in an R-Theta configured system will work simply in addition to an XY place set off, with the coordinate specs merely outlined in polar coordinates.
