the PD002 setting did the trick o.k. i can at least turn the spindle on/off( kind of ) from F5 . i can also increase and decrease the speed but i still need to have the active low setting ''ticked '' for the start / stop output. the spindle still runs on its own albeit at a very reduced speed . i have an LED on board the BOB for the relay outputs and the relay for the ''start /stop '' is constantly on because of the active low tick. It looks like a synchronisation issue between MACH and VFD, i think. ??? if there is such a setting . i also set the spindle pulley tab to ''MIN ZERO'' & ''MAX to 24000'' . there must be some other setting i'm missing. cheers jazz.

Shouldn't do that at all.!! . . . So when you push f5 for off are you saying the spindle keeps running but speed drops.?

Post the XML file for the profile your using for Mach3 so I can see how you have Mach setup.
You'll find it in the Mach3 folder with the same name as the profile you use and ending with XML.
Zip it up to post other wise won't allow you to post.

i made a right balls of trying to copy the XML file and deleted it instead. i tried to restore it but having no joy. i will set it up again and get it up a.s.a.p. sorry for the inconvience Jazz

Mach keeps a backup for you. Just look in the XML backup folder it will be there.

after pulling the little hair i have left on my head and trying everything i thought would improve my spindle issue i have stumbled accross what i think is my issue and solution. i had a single wire run from +10v (bob) to +10v (vfd). when i made off the control cable initially between BOB and VFD i just used 4 core,2 for the PWM and 2 for START/STOP, all sheilded. because i needed another signal for +10v I ran a single cable temporarily to test and this is where i believe my problems stem from. i unknowingly had the single cable next to a power cable and by chance moved it during the spindle running on its own and the problem dissapeared. Now i know why experienced builders keep the VFD outside the cabinet. i didn't realise how sensitive these signal cables are. once again a big thank you to Jazz for the time given in relation to this. everyday is a day for school .
