Just blown up my inverter

[EddyCurrent]

Can you post a drawing showing how you connected everything ?
Also which parameters did you change and what value did you use ?

[Lodds]

To be honest not really sure what I had changed, I was digging a hole that just got deeper. As I said it did work when I first started.

Hopefully the file got attached.

[EddyCurrent]

Can't see any files, did you check it was attached before logging out ?
I didn't mean what did you change at the time of the fault, I meant which parameters did you change from default at the time you got, "the programming out of the way"

These are the settings I changed.

General VFD setup:
Here's the correct settings for the Huanyang VFD that always seems to come with these kits.[/FONT]

PD013 - 8 MASTER RESET <<< DO THIS FIRST [Jonathan Edit: I prefer not to input this reset command, as often they've set a lot of the settings for you, so it saves time to leave it and you'll spot any settings that are wrong when you set the rest, so there's no risk]
PD005 - 400
PD004 - 400
PD003 - 400
PD006 - 2.5
PD007 - 1.20
PD008 - 220
PD009 - 15
PD011 - 120 [Jonathan Edit:*No, this is a common misconception. This setting is the lower frequency limit, so setting it to 120Hz means you can't run the spindle below 7200rpm, which originated from the air cooled spindles which would burn out below this speed. This is not a problem with water cooling, so*you can set it to zero. You wont get much torque below 7200rpm, but down to about 3200rpm is useable for drilling small holes in aluminum if you don't have carbide drills.]
PD014 - 1 [Jonathan Edit:*This is time to accelerate to rated speed. It may be better not to set it as low as 1 second (e.g. 2) to reduce the starting current, or if you don't appreciate the lights dimming every time you press run.]
PD015 - 1
PD072 - 400.00*
PD143 - 2
PD142 - 7
PD144 - 3000, factory setting is 1440 ->3000 gives correct RPM of 24000 at 400hz

Control Settings:
For spindle Start/Stop using Mach controlled relay connect DCM to FOR with the relay wired between the two. NOTE: Wiring DCM to REV will give reverse spindle rotation.

For variable speed control using a 10k ohm pot connect ACM and 10v to the pot with IV on the Wiper.

PD001 - 0 = Start from VFD Panel(Manual control), 1 = Control from inputs(use if Mach is start/stopping your spindle as explained above)
PD044 - 2
PD045 - 3

wiring diagram ? or did you just connect the power in and motor without adding any control wiring ?

A proper diagram is essential, for your own sake too, but it seems you don't have one.
So just to be clear, you connected the spindle cable cores to UVW at the inverter, and where did you connect the other ends at the spindle itself ?. (I don't have one of these spindles so I'm not sure what terminals are provided) Did you use any of the cores as an earth wire ?
