    Re: CPU alarm 1-1 bus error

    Dear cncts11,

    So it was the TFP board itself as I suspected. I replaced it and the machine booted. A client of mine who works with fiber on a regular basis wanted to offer me some multimode fiber...

    Re: need VFD recomandation

    On your motor name plate it says 380/220V. That usially means 380V in star or 220V in delta. Your VFD will be 220V input 3x220V output. So you need to put the motor in delta (220V) mode for it to...

    Re: need VFD recomandation

    That is way to complicated. Keep it simple. Just get a 1-1.5kW VFD with a single phase 220V input. Just use it on single phase all the time. Put the motor in delta (220V) and that's it. Additionally,...

    Re: need VFD recomandation

    Hi there,

    The speed on induction motors should be altered by altering the frequency, not the voltage. If you lower the voltage, the motor will lose power and start turning at a lower speed but...

    Re: need VFD recomandation

    Oh yes,

    I do not recommend more than 25% over-speed, since the motor (and machine) is not mechanically built for this IMO.

    Re: need VFD recomandation

    You need to be careful when putting old motors on a VFD. They were not built with regards to VFD. Their windings can heat up when used on a VFD.

    If you plan on using it on 220V single phase, you...
