    phase chopping l297+l298

    i have a bipolar motor and i would like if it is possible to make phase chopping or inhibit chopping when the motor is working with 2 phases - full step mode. And if it isn`t possible how can i control the current in the windings?

    hi
    explains better thing you want to do.
    do you want to change the way of pilotage, while the motor is in rotation?.
    or while it is being firm?.
    it considers that the formality inhibit and almost useless.
    in phase chopping mode, the tide in had gone out since 298, it is regulated through the VREF, in entry on 297.
    looks at my site !!!
