Hi again Muzzer,

The Threshold Voltage is the only Parameter I've not changed, this is set at 720v I was unsure what it did, so didn't want to mess with it... I can bring it down to closer to 400v and see if that helps...

I have seen something (Page 47) that states the most power allowed for is 5 times the 'Breaking Power Resistance' (01_33) which in my case would be 5kw but I was a bit worried to increase this setting by that much, but I could do it in small increments, maybe...??

I've changed the 01_14 - 'Decel time 1' to 4 seconds (this is as low as I can get it without Overvolt) and 01_16 - 'Decel time 2' to 0.5 of a second.

at the moment I'm still not seing any noticable reduction in stop times, I can see/hear the resistor kicking in, as soon as I hit stop but till it reaches 3000rpm it doesnt kick in fully...

I've also contacted the supplier, but they usually take a few days to reply...

It's a CNC Spindle Router, so there isn't a lot of inertia compared to something like a lathe.
