Hi,
I'd be trying to cut the panel in one pass, ie top layer aluminum, the core and the bottom layer aluminum all in one go.

Hi,
I thought that prb.LoadSettings was the format that you would use if 'prb' is a module.
I never used modules and am unfamiliar with the syntax.

Hi,
do you have any custom modules? They will have to be copied separately.

Hi,
do you have an individually named screen set?

From what you describe I don't think you do. In the lower right of Machs screen there is a window
telling you the screen set in use, I'm guessing something like wx4.set.

Any and all screen modifications you have made over the last few months have been made to and stored in
the screen set file wx4.set or whatever.

When you updated Mach you got a fresh (and updated) copy of wx4.set and all your modifications have been
overwritten.

If you do not have a backup copy of the screen set from before you updated you're stumped. You will have to redo
all those tweaks. This time make an individualised copy of your preferred screen set so that it does not get overwritten
again.

For instance go to the screen folder and make a copy of wx4.set and call CCWoodwx4.set and use that screenset
in your profile.

Hi Mick,

After taking a look at the CN7 plug I have noticed that the jumper wire for the Internal Brake is pre-connected. Should this have been disconnected prior to use?

No, according to the pic you posted  earlier  the installed link is for the internal resistor. If you have not disturbed it then it should be correct.
As I view it you could miswire that link so that there is no resistor either external or internal and that could cause a damaging fault. If you have not touched
it however it seems unlikely.

Those shots of So Move screens suggest that the software is very slick.

I'm not surprised that you cannot erase the error log, what would be the point of retaining a log only to have a customer erase it at will? The log
looks like a buffer, as more recent errors or warnings occur the old error codes will drop out the bottom.

The only one which surprises me is the foldback current error. From what you have described there is no way you could cause the servo
to absorb enough current that current foldback became active in the drive. That would be the instant the drive 'threw a leg out of bed' I guess.

Hi,

I was thinking more so with the connections coming from the CN1 50 pin plug.

I imagine that there is any number of ways that you could miswire CN1  that might even wreck the input/output circuitry of CN1 but
that could not cause a short in the power section.

Would there be any specific parameters that would need setting or de-activating that may have caused this?

There again there might be any number of possibilities for it not to work but absolutely none of them should cause a fault in the power section.

Hi,
this might be the same:

Next time buy something made in the US or Europe that has a manual!

Hi,
in order to take out the breaker the DC Link has to short and as you describe the drive still powers up so the fault is unlikely the rectifier
or pre-charge components of the DC Link circuit.

Referring to the diagram attached if two 'opposing' IGBTs conduct simultaneously, for example the two highlighted, the DC Link would
short and certainly take out the breaker. The build up of current is that rapid and aggressive that the damage is unrecoverable.

As a matter of design that two IGBTs should conduct in that manner is an absolute failure, usually indicating a fault in one or both IGBTs. Its
extremely unlikely the control system would trigger both IGBTs together and certainly nothing you can do would cause it. If you have correctly
connected the servo, and from your description you had, otherwise it would not have worked initially, then there is no way your 'wiring'
could have caused it.

The only other possibility is if the Brake Resistor is shorted. If so, then the Brake IGBT conducts it would short the DC Link and cause a failure.
Do you have an external brake resistor? In its absence you did not install a link or short of any description?

By my reasoning if you have hooked up the servo correctly and not tried to back feed the drive with AC or DC or some other extraneous
condition, and you have not shorted the brake resistor then there is no condition that you have caused which could destroy the power section.
I conclude therefore that one or more components were faulty from manufacture and 'suffered an early life failure' as such faults are described.

Hi,
that doesn't sound too good. You say 'the electric tripped', does this mean the circuit breakers of your 230VAC supply?

That should not happen and may be an early life failure. If you want to claim warranty which I think is reasonable then you can't
pull it to bits. If you did you'd measure the DC link voltage. I would also check that all six inverter IGBT's were not shorted nor the
brake IGBT.

Hi,
yes that is entirely reasonable. With the machine properly referenced 'Soft Limits' are effective which are a software equivalent
of limit switches.

Note also that as you require three inputs for home switches you will loose the input for limits and also for the probe. There will come
a time when you miss the probe.

Still I think this is a good way to proceed. Having three home switches and three inputs is simple and you will benefit from the learning
experience. You might at a later date change your mind but you will benefit from the experience you have gained.
