METHOD AND DEVICE FOR CONTROLLING PULSE MOTOR DRIVE

PURPOSE: To reduce delay in response due to the setting of a mask time which is performed to suppress vibration after the pulse motor drive is completed. CONSTITUTION: A pulse train is generated from a pulse generator 11 based on the rotation command of a pulse motor, a drive current where two phase...

Zusammenfassung:	PURPOSE: To reduce delay in response due to the setting of a mask time which is performed to suppress vibration after the pulse motor drive is completed. CONSTITUTION: A pulse train is generated from a pulse generator 11 based on the rotation command of a pulse motor, a drive current where two phases or three phases are turned on alternately by a drive unit 12 is supplied to a pulse motor 2 for each pulse of the pulse train, it is judged whether the two phases are on or three phases are on corresponding to the final pulse of each pulse train, and mask time TA or TB corresponding to each is set.
