Here is a bifile for a 5i24_25 7I52s 7I52 with the last stepgen changed to a PWMgenNote that the PWM direction pin has been left as plain GPIO as this is usually the most flexible option.

If you wish to do this yourself, you need the XIlinx tool chain, typicallywebpack 14.7 


@PWC

Greeting!!!I am using above driver to get 5 stepgen and 1 pwmgen but i think i am not getting pwm pulse from TX5B of 7i52s.As following mesaflash's readhmid command its shows PIN 23 is PWMgen and as following 7i52s manual Pin 23 is TX5B and as following it i have connected PWM connection to P2 PIN No 21 of 7i52s and GND to P2 PIN No 17 of 7i52s for mine PWM to Voltage converter(Chines Generic module).does mine connections are wrong or i am missing any thing  ?I am attaching mine HAL and INI files and readhmid output file. 

I would check that PWM enable is true and the PWM value
is set to some reasonable fraction of the PWM scale setting,
then measure the output voltage at one of the TX5B pins.
A volt meter will average the PWM value so you should get
0V to 5V (or 5V to 0V depending on the pin polarity) at 0 to 100%
of full scale PWM/

@pwc

Now i could see pwm is working but when I increase spindle speed it increases frequency but decrease voltages while connected pwm pin to TX5B and GND to GND of pin of 7i52s and when connected pwm pin to /TX5B and GND to GND of 7i52s it increases voltages when increases speed but decrease frequency.

Which connection is right or i have to give pwm to TX5B and GND to /TX5B ?

And i am gettin about 100khz frequency while mine pwm module support only 3khz where i could decrease it

PWM has a constant frequency so I don't think its changing

You have the PWM frequency set to 20 KHz in your hal file:

setp hm2_5i24.0.pwmgen.pwm_frequency 20000

i tried to set

setp hm2_5i24.0.pwmgen.pwm_frequency 20000

to
setp hm2_5i24.0.pwmgen.pwm_frequency 3000 and even 2000 but its still same i am getting 60khz frequency and very minor changes in duty cycle as mine multi meter says(i dont have access to oscilloscope right now) i have checked PWM value and is 1100(mine required RPM) and Output rps is 18.36 (about 1100 RPM) but frequency cycle is above 60khz. And "halcmd show pin *pwm_frequency" shows nothing.

Try:

halmcd show all hm2
