    I haven't changed PD004 so it should still be set at the factory default of 50.

    I am about to go to sleep for 12hrs night shift. I will get time to study the manual and work out what I need to set, providing I understand it. It took me some time to work out what "If the single phase source meets two willfully" meant. Luckily another part had a better description that was easy to understand.

    I will double check PD004 in the morning if I can keep my eyes open.

    Most newbys have a long familiarisation period with VSD's. I don't expect to be any different.

    Its a shame I cannot get the net at work. I could go thru old threads when I am bored.

    First lesson.............. never trust the manual
    Its a pretty fair bet the manual says PD005=50 by default.(and the default maybe 50 for all I know.... but I know all my hangetc came set at 400. I've never reset one so I dont know what it is)

    Always look in both the function list and the description of functions to see if at the very least they agreee with each other lol.

    I need to buy an ammeter and a tachometer. I have got the ammeter that gallegos posted the link to in my Watch list on EBay.

    Has anyone any suggestion as to a specific tacho, or should I just get any one off EBay.

    You mean a hand held one or one for mounting on your lathe?

    Stuart

    p.s. there is a corrected manual around on the forum... looking for it ATM

    I have some square industrial power socket boxes and I think some matching plain lids. Should do me. There is a double one mounted on the lathe that was put there to connect the chuck guard. It has 2 holes in it. Switch and something else. E Stop I think. I could leave the E Stop there in case the amps get too high.

    Tacho- Hand held. Will be essential to determine speeds I think. I have one that is designed for a bicycle. It needs a magnet for sensing.

    An updated manual would be fantastic Stuart. My manual does not even list my model VSD. I cannot find a model number on the VSD. The only reason I know it is not listed is that there is none listed using single phase as big as mine. I guess they had not got around to adding it at the time.

    Thank you Ray.

    For a hand held tac I have one of these(though I've seen them modified for fixed mounting)

    Is your VSD single phase input. Its not 240V 3 phase input?

    My thanks to Ray.


    The VSD is single phase 240v or 3ph 415v but not 240v 3ph.

    PD004 was set to 400. Fixed now. I had a read of the manual right thru, sort of. I am a little bit better off for it.

    Well that sounds a little strange to me, as long as you're sure its rated for single phase input.

    It's running as expected now?

    The good news is most of it you are unlikely to ever use.

    I may have been mistaken about the rating. Another check of the manual and it says "Single and 3 phase 220v/50Hz". However I cannot find a model number on the vsd so I don't really know which one it is or if it is even listed. It was definitely bought as a single phase input vsd. Last nights reading did tell me that pd175 gives the model number. I will check.

    It's running as expected now?
    No change.

    Yes. That was the "sort of". I did skip quite a bit that looked pointless.

    Cheers

    PD 175 returned a result of 0. Fat lot of good.

    PD005 (Max Operating Frequency) was set to 400. By mistake I set it to 50. PD004 is Base Frequency. PD003 is Main Frequency. I was checking Main Frequency but had the number wrong. It is set to 50 because I had been running the motor at that. Anyway, when I accidentally set PD005 to 50, the motor ran much faster. I don't know if it is the right speed, but it seems like a good speed to me. I then reset PD005 to 100. The motor ran at the same speed as when it was set at 50.

    Not sure I understand all that.... but if its working, thats all that really matters.
    Now to find out if it has enough power for what you want.

    I am now thinking about the external control for the vsd. My lathe has a reverse lever to the right of the apron. I am thinking that this means I don't need to fit a motor reverse, but there may be reasons I have not thought of. If not I only need a simple start, stop switch, with the E stops wired in series to this. My manual states that contactor switches should not be used to isolate power to the vsd.

    "No contactor should be installed between the power supply and the inverter to be used
    for starting or stopping of the inverter. Otherwise, it will affect the service life of the
    Inverter."

    Comments?

    I will need to set the relevant parameter to prevent auto restart and use the lathe brake if required.

    Speed control seems easy now that I have discovered (and been corrected) that 3 wires are needed. VR+10v/5v to one side of the pot (10 ohm linear now available at Jaycar), ACM (GND) to the other side and VI to the wiper. Set pd002 to 1.

    I have a plastic housing that may do for the vsd.

    VSD Housing 1.jpg

    It has been sitting around collecting dust for a long time. It used to be used for some sort of pump control for a hydro system If I remember correctly. This was in the days hydro was used to grow tomato's, cucumbers etc. It will need a good clean up.

    VSD Housing Inside.jpg

    The vsd sitting inside. There will be 85mm cleared at the top and bottom, and 70mm each side. The manual suggests 120mm top and bottom, and 50mm each side. I plan to fit ventilation grids on the bottom and at the top rear. I hope this will be sufficient. I have worked out that the control panel does detach, and how to do this. I am not sure this will be required tho. I will cover the holes in the door and have a clear plastic cover over a hole that line up with the input panel. open the door to access. This housing will sit on top of the existing electrical cabinet in the position of the orange housing in the picture below.


    Switch Panel.jpg

    This orange housing was fitted to fit the electrics for the chuck guard. I may refit the guard, but will not have a switch on it. The start/ E stop switch housing was also fitted by my work. I will have to have a look behind it before I decide what to do with it. I would prefer to remove it and use the original panel if possible. Mounting the housing where the orange box is will enable me to run wires straight thru to the electrical cabinet below. I just need to make sure there is clearance for the cabinet door to swing open. There should be enough switches for what I want except for the speed control pot.

    I have got the motor back where it belongs, but not bolted up or the belts on yet. I plan to get it all connected properly and then check what sort of power I seem to be getting with the lathe running. I would like to have an ammeter fitted before this happens just for safety. We are currently suffering a cash flow issue, so I will have to wait a bit for these niceties.

    I have also worked out that the operating panel for the vsd does detach, and how to do it. I am not sure if this will be of any benefit in this situation tho.

    I think you might have misread that, there is no problem having contactors upstream of the VFD.. the motor should be wired directly to the vfd, with no switching in between.. ( ideally that is ).

    Box looks ok, bigger would be better.

    That 10 ohm pot might be a bit low... 10K would be better..

    Ray

    PS I'm not seeing some of your pictures? Second one is ok, first and third say invalid attachment?

    Nope thats what is says. But what(I assume) they mean is "don't use the 240V supply for normal control of your VSD"

    If the current tests I am doing are anything to go by you might not have enough power Dean, but there is one way to find out
