ok (this is petes wife as he has gone to cool down and pour a big drink) i have just been going through the settings on the box and this is what i have found fingers crossed you can find something wrong here ,,,,,,, F000 is 0 ,, F001 is 1 ,,, F002 was 1 but i then changed to 3 and for the first time the spindle thing was making a noise but then the estop writing came up on the display and it stopped,,,,, THEN coz i didn't know better i press F003 is 50.0hz and F004 is 51.4hz ,,, i stop after that ,,,

To be honest, the numbers for F000 through F004 all look good. You can recover the F002 to 1 at any time to change the speed control back from the pot to what should be software control through Mach3.

The problem that I'm thinking, as posted above - up until now the spindle hasn't been driven, by changing F002 to 3 you've removed the software control and put the rotary control into play - and that is as the VFD is configured in the factory - default/standard set-up. Obviously the machine builder configured it differently to be controlled by software - but either/or should be equally valid (they work very much the same way). But whilst the software/Mach3 control system is still a bit unknown to us, by changing to the F002=3, rotary control (pot) we've removed some unknowns, and now the spindle should be under complete manual control. With the VFD switch OFF, and the rotary knob fully anti-clockwise, the spindle should be off. Turn the VFD switch on - the spindle should be "on" but not turning. Rotating the knob clockwise slowly would be expected to result in the spindle spinning faster and faster. What I think OP is saying is that, either with the VFD switch ON, or at least ON and with the knob rotated away from the zero position, that the VFD displays a fault?

If the above is accurate, this moves the investigation away from any Mach3 set-up issue (at this time) to the VFD and spindle.

this is still Louse (Petes wife) All this you have wrote (copied above i hope) is doing as you say EXCEPT the spindle makes the noise of spinning but does not spin and when you turn it up to run faster the estop display comes on the box and stops it all

[Doddy]

Thanks - that makes sense (although clearly not what we want). My problem is that you earlier said e-stop, where the manual (if applicable - and that's by no means certain) only indicates the following messages on the 4-digit display...




...and...




Is it possible that the display indicates one of these (left column) rather than "e-stop"?

[Doddy]

I should say - that rotating the knob and you get the noise (but not the rotation) is kinda promising. Though we should limit the number of faults we stress the motor/VFD to. It does suggest at least an approximation of correct behaviour.

There's a a few more checks to try - but first I'd like to bottom exactly the error message (as above). Or, just confirm that the error is "e-stop" and we can consider that the manual above is inconsistent with the VFD - and move to reject that.

looks like E.FoP to me ,, so sorry i just took it it was the way it was wrote to say estop
louise

[petesos]

and i must add i can touch it with no probs but pete gets static from it

Now you're worrying me. Sorry, quick reply just to suggest for now not to operate this until we try a few more things.

[Doddy]

Please describe "get static" - normally a static shock dissipates very very quickly - an immediate jolt followed by nothing. Does Pete get anything more sustained? (lasts more than a fraction of a second)?

EDIT:

Sorry, and from touching what?

[petesos]

When the spindle on/off rocker switch is off nothing happens when i rub my palms over the bed of the cnc or my arms .But when i switch it to ON and i rub my hands on the same part of the bed i can feel some static but when i put mt forearm on the same place i get i good old jolt from it .If i wear my slipers there is no problem but in bare feet is when it happens
