Hello Clive,

Thank you for coming back. It is genuinely appreciated.
I'm not with the machine right now (so no answer re the version of AC10 - I'll get back around lunch time - nursing a laser machine this morning. That too fell over at the same time - flow sensor failure here. I only lost a couple of days on that one)
I'll do what I can to answer the other points:
Poles? Hah! Nope. So we tried to extrapolate the poles from the auto-tuning info in the manual / part of the initial setup procedure and the best we can ascertain is 2...but unless you can enter the |24,000" it won't accept the value, resting at 4 poles and that doesn't work. Motor gently starts to heat up.
I'd read on somewhere that you can enter "alternate" values with a sub-division of the motor speed, i.e. a value that would be accepted but that hasn't worked. It has to be programmed in!
No you cannot program from the display, that is the whole root of the problem. It will not accept this number of fields (5)...hence the need to buy the programmer. How crazy is that?
All I can say the original Chinese VFD was fairly old and the failure happened mid-cut, so everything was working well. Literally, it went "BANG', tripping out the ring. Checked, Wires are all intact.
For speed of delivery I bought the AC10 from RS (yes, eyes watering) and then realised the complexity.
(I've even tried buying a 500W, DC air-cooled motor. The vibration is something else. So that is consigned to the: "I'll sell it on Ebay.."someday"" box!
Ho hum.

Here's the link to the manual:
