ABSTRACT:
A motion control system in which motion is set by the number of whole steps to be produced in consecutive time intervals where the selection for each time interval is from a plurality of different numbers arranged in a sequential progressive order with a manual control causing the system to select numbers for consecutive time intervals from its last selected number sequentially through the order to one alternating repeating number for the lowest speed and a higher number for a maximum speed, in either direction. The system further enables the operator to adjust the rate of the steps in a time interval and the duration thereof, thereby altering motor speed without changing the number of steps in a time interval. When the operator releases control, the system automatically makes the motor assume its stopped, non-moving state.
