Abstract

PURPOSE:To simplify the control in the process before stop, without taking the accelerating state into consideration, by starting detection of the rotational state after reaching a state of uniform motion. CONSTITUTION:When applied pulses P1, P2,... are provided to the pulse motor, it starts to rotate in the rotary direction which has been decided in advance. Although the pulse motor is accelerated by the applied pulse, in this case, it detects that it is being accelerated by an acceleration command pulse and the number of applied pulses, and during that time, it disregards a rotation detecting signal from the detector provided to the pulse motor. For instance, after 8 pulses have been applied, the pulse motor performs a uniform stepwise motion. In order to stop the pulse motor by the specific phase from the uniform stepwise motion, it is executed by deciding the necessary number of pulses for the deceleration driving profile, by the relation in case when the rotation detecting signal and the specific phase have been excited.
