The stepper daughter board with position verification has all the features of the standard stepper daughter board. Position verification is added to a stepper axis by providing encoder feedback to check the position of the motor.

 

 An encoder port on the daughter board allows the position of the motor to be checked on every servo cycle. If the difference between the demanded number of steps and the measured position exceeds the programmed limit, the Motion Coordinator can take undertake a programmed error sequence.
