APPARATUS AND METHOD FOR DRIVING A LEADSCREW |
摘要 |
A leadscrew driving arrangement which is corrected to eliminate the effect of pitch errors. The leadscrew (32) is mapped to create a table of differences between the leadscrew angular of a perfect leadscrew which has been advanced the same axial distance. The differences are used to create a correction table which is stored in a PROM (44). During operation of the leadscrew (32), the correction table is used to adjust the leadscrew driving signal. |
