Not sure I understand
The encoder scale must be set to match your encoder or the spindle_at_speed (or tapping or threading) cannot work
Normally this is set with the INPUT_SCALE parameter in the spindle section of the INI file
Can you post your complete HAL and INI files here?

Linuxcnc the coast I think I have everything configured properly.
I have a problem with the drive:
Max spindle speed: 2500 rev / min
Speed requested by linuxcnc: 300 rev / min
Speed displayed on the LCD screen of the drive: 1500tr / min
Can you check the wiring diagram attached

What is the voltage between spindle-out and spindle- when you command 300 RPM?

Hello,
In file attached my Ini.
For 300 tr/min i have 7,45 V in spindle - and spindle out

OUTPUT_SCALE = 400
is incorrect (the is the spindle analog output scaling)
this should be
OUTPUT_SCALE = 2500
Its the spindle INPUT_SCALE that should be 400 (assuming 100 line quadrature spindle encoder)

Hello,
Ok but I have no INPUT_SCALE in my ini file ???

Not sure why (spindle encoder not selected when you ran pncconf?) but you can certainly add it
You will probably also need to add the setp line in your hal file that sets the spindle encoder scale

ok I'll do it tomorrow.
Have you an example please?

Can you post your current hal file?

In my attached file HAL.
To test I made a machine with pncconf.
In the INI, I do not have the variable INPUT_SCALE
