Yes exactly that, I have helped several people who have bought these and none of them have come setup.
The VFD will most likely be set to the default 20 seconds for both acceleration and de-acceleration so you might want to change these to get to speed quicker.-use common sense, if you lack it, there is no software to help that.

The usable range is 6k to 24k rpm. Go much below 5k and there is no torque without playing with VFD settings.
The settings for acceleration and de-acceleration are PD14 and PD15. Set to 5 and 10 respectively, don't go too low on the acceleration otherwise, you will get over current/voltage error's as the VFD dumps loads of current/voltage into the spindle trying to meet the request to get upto speed in the short time period.-use common sense, if you lack it, there is no software to help that.

i will never run it at anything less than 24k.
the acceleration seems to be fine, no issues there. but it doesnt seem as powerful as my previous router?!
ive come from a denford microrouter with a 1.1kw spindle, to this with a 2.2kw spindle.
using exactly the same wood and cut settings as i would have used on my denford, the 2.2kw struggled and made a hell of a noise!
i was expecting better cutting performance from a 2.2kw watercooled spindle.

I doubt it's the spindle at fault unless your settings are wrong, if not I'd look more to the machine and chatter, etc for the noise. Denford router is a lot stiffer than that machine.
I know someone who I converted a Boxford A1 router for which is very similar to the Denford micro who has just bought the same machine as you, all be it from another builder who builds them much better than your supplier.! . . Well, he at least puts all the bolts in and supplies them electrically safe, set up ready to use.
Anyway, he has just approached me to build him a machine because he can't live with the chatter he's getting from it. He mostly cuts 3D models and the machine just can't handle it.-use common sense, if you lack it, there is no software to help that.

thought id get a quick job in before the new parts arrive.
turns out the machine is just dangerous, the cable to the steppers is not sufficient and gets warm. the cable is only rated for 3amps, also see the below -

Andy, I'm sorry to see you are having these troubles and my only advice is to send it back under your statutory rights if possible. The machine is clearly unsafe so he hasn't got a leg to stand on.
I would also like to salute and thank you for standing up and showing how poorly built and dangerous these machines really are.
Being a machine builder I am in a very awkward position when it comes to pulling another builder's machine down because to others it can and does appear like I'm just saying it for my own gains, however in cases like these machines I just can't sit back and say nothing. So when someone like yourself has laid out good money and is good enough to stand up publicly to show others then it should be recognized and appluaded.
Now, if you do manage to return it then get in touch with me and I will sort you out with a proper machine at a discounted rate as a real thank you.-use common sense, if you lack it, there is no software to help that.

the steppers are 86HS115-4208 - which could draw up to 6 amps, depending on how they are wired.
the cable used is LAPP u242 - so 4x 0.25mm cables - this appears to have a rating of about 3-4 amps.
which probably explains why the cable is getting warm after 35mins of use.
