    Stepper Motor Driving at High speed

    high speed stepper Hi Hunter The schematic is the same as given in L297 datasheet. The values of RS1 and RS2 are 68ohms and 2W. the clock pin is directly connected to a port pin of microcontroller (I am using Texas MSP430F149 controller). The clock applied is a PWM similar to the one shown...

    Stepper Motor Driving at High speed

    driver stepper high speed Hi Thanks for the reply. But if you refer to my previous post then pls check that there is a difference in the pulse that is applied to the CLK pin when the motor is driven at high speed. I have trapped this pulse on the oscilloscope. I generated using the same pulse...
