Abstract
According to a control device for a stepping motor of the present invention, in a first operation mode, a microstep driving section,is selected, and an output of this microstep driving section,is applied to a driving section,through a command selector,, whereby a stepping motor,is microstep driven by this driving section,. Furthermore, in a second operation mode, a forced driving section,is selected, and an output of this forced driving section,is applied to the driving section,through the command selector,, whereby the stepping motor,is forced driven by this driving section,, i.e., a high-speed rotation of a rotor,is started from any rotation angle with the microstep driving. Furthermore, in a third operation mode, a driving pattern generating section,is selected, an output of this driving pattern generating section,is applied to the driving section,through the command selector,, whereby a high-speed rotation driving of the stepping motor,is continued by this driving section
