PURPOSE:To store data by compressing without loss of accuracy by converting the data to be stored in a memory for storig the data for switching the exciting phase of a motor into an initial value and the difference between the data and storing them. CONSTITUTION:An oscillator 1 supplies a clock to a counter 2. The counter 2 can write or read out the data from the controller 3, subtracts by one from the clock of the oscillator 1 at the data written by the controller 3, and feeds out a signal for notifying that the data becomes zero to the controller 3. The controller 3 converts the time data to be stored into an initial value and the difference between the data, stores them in the memory 4, and sequentially produces the data and recovers. The recovered data are supplied through a distributor 5 to a stepping motor 6. |
