Did you read my correction.?

Also VFD will need to be powered up.

0.0 v with M5
6.4v with M3 S12000

Ok well this is where it gets a little sketchy with this BOB because I'm not quite sure which settings to tweak to fine tune the voltage.

Start by changing the Spindle Pulley Max speed to a higher number then check the voltage and see if it goes down.?
We are looking to get around 5V With S12000 and 10V with S24000.

I'll try and see if I can find out how the speed Ref voltage is handled and changed with this BOB.

Edit:
Ok well after bit of thought it occured to me that the Steps per setting in Motor tuning for spindle could be used as the Carrier frequency and with 2000 steps which I think you will be set at will give around 6V. So Leave spindle pulley Max set at 24000 and change the Steps per setting to 2400 and see what happens.?

Let me know.

my meter started to fluctuate and give different readings so i had to wait and get a new battery this morning and double check the readings against the readings from last night .
New reading as follows:( checked at least 20 times!!)
1.5v with M5
8.1v with M3 S12000.
appologies for the delay and inconvenience.

i set the Steps per in motor tuning to 2400 and the readings remained as follows :
1.5v with M5
7.9v to 8.1v , M3 S12000.

In Deans temporary absence change the steps to 1600 and report back the Volts as before. But say in your post what you have done so Dean will know. Clive
