    What example project are you using? Yes, the resolution of reference speed cane be set to 1rpm, even smaller also.

    Hi Yanming,

    I use the Lab 13b with an Biss Encoder. The Encoder has an resolution of 16384 points each Motor turn.

    With this Encoder Resolution i think its possible to to spin with an resolution of 0.0001.

    What do you think?.

    Can I also set the Motor Speed with counts.

    16384 counts = 1 motor revolution. When i set it to 16384 the Motor must spin with 1 RPM.

    I think the set speed is converted into counts. How can I see it.

    Thanks Alex.
