Direction: In the feed drive of a Point-to-Point open loop CNC drive, a stepper motor rotating at 200 steps/rev drives a table through a gear box and lead screw-nut mechanism (pitch = 4 mm, number of starts = 1). The gear ratio

U = 1/4. The 1 stepper motor (driven by voltage pulses from a pulse. The frequency of the pulse train from the pulse generator is f = 10,000 pulses per minute.
