Two stepping motors are used in an open-loop system to drive the leads crews for .r-y positioning. The range of each axis is 250 mm. The shafts of the motors are connected directly to the tea screws, the pitch of each lead screw is 3.0 mm, and the number of step angles on the, tipping moot IS 125.
(a) How closely can the position of the table be controlled, assuring there are no mechanical errors in the positioning system?
(b) What are the required pulse train frequencies and corresponding rotational speeds of each stepping motor to drive the table at 275 mm/min in a straight Line from point (x = 0,y = 0) to point (x = 130mm, y = 220mm)?
