QUICK DETAILS

 

 

Accuracy and Resolution Stepper systems have a difference between their theoretical and actual resolution. For example, a twophase, full stepping, 1.8° step-angle motor may have 200 possible positions in one revolution (360°/1.8°), but whether or not it’s achieved depends on how the motor was sized for the application. The same is true of half stepping and microstepping motor drive modes. A 1.8° microstepper, though specified as having ten microsteps per each full step, cannot necessarily find any position within 0.18°.

 

Additionally, several commanded microsteps may be required before there is enough torque build-up to overcome friction and load inertia. In a real-world situation, the motor could easily jump one or more microsteps beyond the number commanded and stabilize there. When positioning-resolution
