    Asto should not make a lot of difference, most of the connections and settings are the same across a lot of the different models. You have enough manuals here now to what you need. the only difference will be the frequency settings for the speed control which won't be hard to deal with. Post a pic of the one you have.

    Also i think the VC150 = Cub 1.5 amp version

    Sure i will do that tomorrow

    Thank you all

    regards

  3. @swarfing Exactly so, I thought the Cub is the VC150 (except its not 1.5A but 1.5kW (2HP) LOL), IMO branded differently for different markets...

    Yes it is the 1.5kw Irving looking again. all config is the same as far as i can see on them all.

    I hope these IMO images have a lot to say.
    The schematic came out of the Parajust manual. The pdf extracts are for the Parajust
    As you all see, control impendance is double in the IMO as Parajust needs 5K pot in order to bring the motor to full stop.

    Ok this is much older than what we have been looking at. But you have all the information to connect this up so don't understand your problem with it Asto? Swap the potentiometer out for a 10k one

    You mean an external pot?
    With an external linear rotary pot of 10K runs fine.I've done this already.
    My problem is, that I totally disregard which way to proceed in order to alter settings that will cause the IMO find sufficient the Orac's 5K digital pot and bring the motor to a complete stop...Cause, when I deccelarate through the machines (-) button the control outputs a maximum 5K resistance. I really do not know if it is possible to alter this value to 10K.

    Maybe i am not understanding this completely. The wiring in the Orac should go directly to the VFD for the spindle control yes? or is it going by a different circuit first? Is the speed adjust from the software of the machine or just analogue control?

    That's right Swarfing.
    The Orac's controller decides what resistance value to apply at the inverter input. And is wired directly to it even though the VFD may be removed and operate as stand alone to control motors of some other system.
    Even when the machine is at manual mode the controller does the accel/deccel i guess by digitally switching resistors internally. It has to be this way how else would it be!
    Is that the question or I have missed something due to the foreign language factor which applies for me here.

    Ok i understand now thank you. Does the machine speed controls ramp up and down linear or are there distinct steps in the ramping?

    My thoughts were that the speed pot from the VFD ran directly to the machine controls. I do not know this machine and find it difficult without seeing it. Could you do a pic where the wires go from the VFD to the machine controls?
