I edited the Spindle part of my hal as following:
When i start my spindle it starts at 9xxx rpm instead of 6000 when i type M3 S24000 i only reach 22xxx rpm and for everything else the values are higher than what i typed in.
This is the Spindle part of my Ini:
I will attach the full hal and ini aswell.

I cant be doing everything wrong here 
, is everyone else controlling their vfd via modbus ??

It sounds like the drive runs at 6000 RPM for 0V input
if so the lincurve values are wrong since you want a
Y value (output) of 0 at a commanded RPM of 6000
Also if you have a output scale of 26000 and a maxoutput of 24000
you can never get full output (these should both be left at 24000)

the thing is at m3 s1 where it shouldnt be turning i measure 0.03v and get perfect 6000 rpm
at m3 s6000 i get 2.3 v and 10300 rpm and at m3 s7000 i get 2.7 volt and 11000 rpm
i already changed that output scale back to 24000 but it didnt change anything
at m3 s6000 i get 2.3 v and 10300 rpm and at m3 s7000 i get 2.7 volt and 11000 rpm
i already changed that output scale back to 24000 but it didnt change anything

Right, so your linscale values are wrong,
Y should be 0 when X is 6000, you have that backwards
Y should be 0 when X is 6000, you have that backwards

so it should be this way:
# ---auto rpm: 1-6000 = 6000 / 24000 max
setp lincurve.0.x-val-00 0
setp lincurve.0.y-val-00 0
setp lincurve.0.x-val-01 6000
setp lincurve.0.y-val-01 0
setp lincurve.0.x-val-02 6000
setp lincurve.0.y-val-02 6000
setp lincurve.0.x-val-03 24000
setp lincurve.0.y-val-03 24000Please Log in or Create an account to join the conversation.

Point 02 is wrong and will cause you to get about 2.5V with a 6000 RPM command instead of 0V
Do you get 24000 RPM at 10V?
Do you get 24000 RPM at 10V?

the maximum is 23xxx rpm at 9.1 volt

So you really only need 3 points for lincurve (you could actually do the same thing with the scale component since you are just offsetting the analog output by 6000 )
setp lincurve.0.x-val-00 0
setp lincurve.0.y-val-00 0
setp lincurve.0.x-val-01 6000
setp lincurve.0.y-val-01 0
setp lincurve.0.x-val-02 24000
setp lincurve.0.y-val-02 24000
setp lincurve.0.x-val-00 0
setp lincurve.0.y-val-00 0
setp lincurve.0.x-val-01 6000
setp lincurve.0.y-val-01 0
setp lincurve.0.x-val-02 24000
setp lincurve.0.y-val-02 24000

i changed the hal part and now when i start the spindle it starts at 6000 but i cant change the speed anymore.
I can start stop and change direction nothing else.
The Output voltage stays the same whatever i input via m3 sxxxxx
i appreciate the help so far, im trying to get this working correctly for the past 2 days
