OK, there are no PWM's so that will need firmware flashed with PWM.
Download the support files from mesanet.com for the 5i25, extract, there should be plenty of firmware files, so you would need one that has stepgens and encoder same as you have them now and have PWM gen instead of TX/RX stuff.
Flashing is easy:
sudo mesaflash --device 5i25 --write name_of_the_file_to_be_flashed.bit
Almost forgot, ther are also files with .pin in the name that shows the pin assignment .

Wait, what do you need a PWM for anyway?
The analog output for the spindle on a 7i76 is not commanded with a PWM hal pin. Does your drive require an analog signal or a digital PWM?
If you are going to use a digital PWM output you will need to re-flash the firmware of your 5i25 to replace one of the step/dir outputs with a PWM signal.

I am guessing that you have copied sections from a configuration that used a different combination of Mesa cards.
Delete the two lines that set PWM and PDM frequencies.
Then elsewhere in the code replace the pwmgen references to hm2_5i25.0.7i76.0.0.analogout-00 (or whatever your actual spindle output pin is called)

so i think i am making a big mistake i take config with pwm but this is pid i need i start new config like alkabal i see serge452 has omron which is same as hitachi , I think it's getting close to what I need.

I think your current setup is close, you just need to swap the pwm (one way to do analog output) to 7i76 analogout (another way to do analog output)

Oh your welcome for try the last revision :
ini :
Ini halui entry :
--the theory is inverted the comment out for :
--connect jog signal if you have a mpg wheel in the correspondent config
--connect your input signal from 3D touch probe if you have one using
--comment out your signal sent to the card from your regular spindle config and put them to the orient spindle input:
7i76.0.0.spinout
7i76.0.0.spindir
7i76.0.0.spinena
-- for trying to keep the standard please use the good name in your spindle config for sharing some signal
for spindle use a pid configured as rpm
-- find your PID settings
--set your speed and tolerance

But i suspect the way is configured your spindle can be problematic, this need to be tested.
