Applied Motion Products Presents Encoder Feedback

Jeff Kordik, AMP's CTO, demonstrates that adding an encoder to your stepper system greatly enhances performance by providing you with these closed-loop functions: Stall Detection and Stall Prevention. Stall Detection notifies the user/system/machine as soon a motor stall occurs, eliminating the uncertainty of whether or not the motor reached its target position. Stall Prevention actually eliminates stalls by dynamically controlling the stator current and speed of the motor to maintain torque.
