halcmd show all | grep pwm

(the PWM frequency is for all PWMgens)

I've been using AI to solve this issue. They give a lot of imagined stuff when they can't solve an issue.
setp hm2_5i25.0.pwmgen.00.frequency 1000 threw error: ./5i25_7i76PWM_7i74.hal:21: parameter or pin 'hm2_5i25.0.pwmgen.00.frequency' not found

How else do I set the PWM frequency then?

Each CNC will take a specific job, depending on what it comes out from a query in a database. They are all the CNC's in a line, but just one of them will take the job. For example, each CNC, has a different tool, so depending on some given parameters of the material you insert in the query, the database selects the correct CNC to do the job. That's why I need to have them all in a LAN. But at the same time the database is on server with a WAN, so I prefer to use ssh for security reasons and others. So the result of the query sends me data with the selected CNC, and the list of instructions to send to the selected CNC that is the job (instructions) that the CNC should do as well as the connection instructions. Every CNC has it's own IP address, so the idear is to make the connection with SSH. I've seen that they are three ways of setting the Telnet. Not sure how the echo works. Thanks a lot. If you need more data, just let me know.

Could be tuning or marginal 5V at the 7I77 (check when running)
Does lowering the P term make the oscillation go away?
 

In many HostMot2 firmware builds the PWM frequency isn’t a runtime‐adjustable parameter. Typically the pwmgen component would export a parameter called either “pwm_frequency” or “pwm-freq” to let you set the carrier frequency, but in your firmware configuration only the two basic pins (enable and value) are exported. This means that the PWM frequency is fixed by the bitfile you flashed.


That's not true, all hostmot2 firmware with a PWMgens exports pwm_frequency and pdm_frequency parameters. Note that these are parameters, not pins.

Also I wanted to ask the .vhd file you gave is it the complete firmware design files that can be compiled into a bit file in suitable version of xilinx ISE?

No, that file only has the constants that define that particular configurations set of modules and pinout. You need to download the 5i25.zip file from the store or www.mesanet.com to get the full sources.
