PURPOSE:To correct an error from a normal position in a short time by a method wherein the pulse motor is stopped at the predetermined normal position by redriving the same in properly using an acceleration, constant high speed, deceleration control and low constant speed control according to differences of the error values from the normal stop position. CONSTITUTION:The pulses from an encorder 2 of the pulse motor 1 is input to a counter 3(I). The counter 3 generates error pulses showing the errors from the normal stop position. The error pulses are fed to the counter 5(II) and the differences of the error pulses are judged therein. When the error pulses are of more than certain values, the pulse motor is driven at high speed by a speed pattern stored in ROM16, and when the error pulses are of less than certain values, the pulse motor 1 is driven at the low constant speed and driven until stopping at the normal stop position. |
