Step motor driver


Good evening!!!
In a application with a step motor i observe that some times the step motor stop moving. In a cycling programm the movment some times the step motor does not execute!! I observe that if i increase the pulses resolution of step driver the problem is eliminate, but if i increase the speed pulses/ sec  the broblem appears again. The load is small.
Thanks in advance!!

Sorry but cannot understand. I think that you mean that if you try to rotate fast the stepper stops. This is normal. Steppers have a maximum RPM that you may exceed.
