Features

Can implement stepping motor drive systems simply by providing a DC power supply and a clock pulse generator.
One of five drive types can be selected with the drive mode settings (M1, M2, and M3) 1) 2 phase excitation drive 2) 1-2 phase excitation drive 3) W1-2 phase excitation drive 4) 2W1-2 phase excitation drive 5) 4W1-2 phase excitation drive.
Phase retention even if excitation is switched.
Provides the MOI phase origin monitor.
