    Yaskawa VFD's can come with custom software that changes the output frequency range. I'm not saying that it is feasible for you to do this if you buy one (if you manage to do it, please let us know about it), but some companies do this for whatever products they are making.

    So you're not necessarily going to figure out what the frequency range is on a used Yaskawa vfd by looking at the part number.

    The best way is to figure out what motor it used to drive and how many poles that motor had and then a simple calculation will tell you.

    If it's a 4-pole motor, 267ish Hz. If 2-pole, 133ish Hz. the 'ish' is allowing for a few Hz for slip compensation.
    f(Hz) = (n_poles/2)*(RPM/60)
