Excitation Mode: Micro Step

Excitation Mode: Micro step

It is even possible to apply finer granularities of step sizes, usually referred to as micro step mode. In micro step mode the motor can be turned in fractions of the full step angle; these fractions can be as fine as 1/4, 1/8, 1/16 or even 1/32 of a full step angle.
