    Question UCCNC to AVF 5100 via Modbusez, problems communicating

    Hi

    I'm having having troubles configuring my new VFD.
    It's a chinese VFD (Avf 5100) controlling my chinese spindle (2,2kw, watercooled, 400Hz, 24 000rpm). I'm using as stated in the title, UCCNC as control software.

    I've configured the VFD for RS485 ( I think) and I'm using a serial to RS485 converter that worked perfectly with my old VFD.

    I tried alot of different settings in Modbusez (v16) setup. At best the fan starts in the vfd but nothing more.

    Attached some pictures of the modbusez settings, a couple of pages from the manual and a pic from the serial communication from one of my tries.

    Anyone who can help me? Have run out of ideas now.

    Thanks
