    Exclamation Stepper motor stalls while accelerating

    Hello guys,

    This is my second attempt to run stepper motor using a driver I made myself.

    The first attempt was running the stepper motor with a constant speed and it was working fine.

    the second one -which I'm doing now- is accelerating the motor speed with a ramp profile, but the motor begins to lose steps and finally stops!! Attached is a video of when this is happening.
    The driver is 4 TIP122 NPN transistors driven by 4 2n2222 NPN transistors, which are isolated using opto-couplers from the microcontroller.
    The motor is unipolar stepper.

    please help me with that problem.
