A leadscrew connected directly to a DC servomotor is the drive system for a positioning table. The leadscrew pitch = 4 mm. The optical encoder attached to the leadscrew emits 250 pulses/rev of the leadscrew. Determine
(a) the control resolution of the system, expressed in linear travel distance of the table axis,
(b) the frequency of the pulse train emitted by the optical encoder when the servomotor operates at 14 rev/s, and
(c) the travel speed of the table at the operating speed of the motor.
