2-phase Stepping Motor Driver

STK672-523-E

Ex.3: Changeover from 1-2 phase to 2-phase excitation

This driver stabilizes motor phase performance at changeover excitation mode during motor motion.

This driver is not able to detect CLOCK rising edge, if the time between CLOCK and MODE rising edge was less than

4μs.

Therefore, motor phase performance doesn’t change in 1 CLOCK cycle.
