The drive unit for a positioning table is driven by a leadscrew directly coupled to the output shaft of a stepping motor. The pitch of the leadscrew = 0.18 in/rev. The table must have a linear speed = 35 in/min. If the relationship between leadscrew pitch p and number of step angles n, is as follows: n=1250p/rg, determine (a) the minimum number of step angles (pulse/rev) in the stepping motor to achieve the required accuracy, (b) the associated step angle, and (c) the frequency of the pulse train required to drive the table at the desired speed.
