Classification: CPC H | IPC H

Claim 0:
1. A stepping motor control device which controls a stepping motor including a rotor position detector by micro-step driving,
the control device including a memory,
the control device comprising a plurality of operation modes including an adjustment mode and a use mode,
the control device being configured or programmed to, in the adjustment mode, generate control data for controlling a winding current of the stepping motor based on a command and a detection value of the rotor position detector so as to perform a closed loop control for a stepping motor acceleration operation and a stepping motor deceleration operation according to the control data, wherein
the command is adjusted to attain a predetermined response of the stepping motor, and
the control device is configured or programmed to save, in the memory, the control data that is generated when the predetermined response is attained,

the control device being configured or programmed to, in the use mode, perform the stepping motor acceleration operation and the stepping motor deceleration operation so that a winding current observed in the adjustment mode is reproduced by an open loop control for controlling the winding current of the stepping motor based on the control data generated and saved in the memory in the adjustment mode, thereby reproducing the predetermined response of the stepping motor.
