How do I accelerate a stepper motor?
As the speed increases, the currents will decay, due to the motor back-EMF and inductance (which is very significant).
Sometimes, at particular speeds, step motors exhibit a dynamic instability. … That is, they start hunting...faster, slower, faster, slower, etc. until the motor "stalls". The resistance seen by the motor, looking back into the drive circuit, is the key factor here. …
