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 is mapped to create a table of differences between the leadscrew angular position and the corresponding angular position 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. During operation of the leadscrew, the correction table is used to adjust the leadscrew driving signal.
