a 1.5kw 60000rpm motor has 0.24nm torque.
at 36000rpm that motor STILL has 0.24nm torque and puts out 900w.
at 18000rpm that motor STILL has 0.24nm torque and puts out 450w.

220v x 5 amps = 1.5kw (345vdc bus minus losses)
135v x 5 amps= 900w. the motor is still drawing 5 amps here. it is drawing over 1000w, but only OUTPUTTING 400-500.

There is nothing to add here. that is the EXPERCTED behavior. but it's not doing that. Clearly when you alter the base voltage on this delta drive it is not simply reducing the speed, it is doing something else, similar to how cutting the bus voltage on a BLDC motor will cut the available torque, where the normal way you reduce speed is to alter the duty cycle, keeping the peak bus voltage.

I am not an ac motor expert so I do not know the "why". It may be literally the same thing as the DC motor.

The correct way to set this up may well be to keep it at 220v for 599hz, but then set the voltage for 598hz to 135v... but I'm done messing with it. Don't care anymore.

lenze is going to make me a custom drive I hope and i can move on with my life.

Searching this forum for DKMS is another option

its RealTek Ethernet hardware. and i'll go through the bios again. i think i saw a couple things in there i can turn off. i assume, just google DKMS drivers for debian.......

You need to disable turbo boost, C states > C1 and speed-step

All power management is disabled in BIOS but I do have Intel turbo boost, C states, and Intel speedstep enabled. Here is the halcmd show param info 

and here is the hardware clockspeed info 

1. The symptoms (not finding any sserial remotes)  do point to 25 pin cable issues
(checking the encoder inputs on the 7I77 would  verify the connections there)

2. Can you post your hal/ini files
 

I need help answering some EtherCat questions; I plan on using Beckhoff ek1100. However, the servo drivers I have support PWM only and not EtherCAT. Is there a slave device I can use to help generate the PWM needed to run the drives? Or what options do I can. 

Hello everyone, my setup still doesn't work I don't know why, it is like the 7i92T doesn't communicate with 7i74 + i/o boards and 7i77 I did the mesaflash and everything and the pncconf, buildbot... I don't know if I need the smart serial install? (I couldn't find how to install it) or the pin file? I installed the Mesa CT also, I checked the DB25 connectors they are wired correctly...

(I copied the hal and ini files from "anfanger" he had a similar machine and all the same boards as I use")

Use the hm2_rpspi driver, the other driver will is it not suitable, if it was we could use it with the RPi5.

You need to enable the SPI interface by editing config.txt

If you run menu-config using sudo there should be an option to either edit config.txt or enable interfaces, uncommercial the line that refers to spi.
Reboot and you’ll have your spi enabled.

Here’s a link to an iso that needs testing that attempts to solve that issue

yes, but the torque is also calculated from the power and speed. And if the power decreases, you have to change something else to get the same torque. I don't think it's possible with the same motor and VFD. A performance diagram of the motor should explain that. I don't think that a 900w motor with the same design has the same torque as a 1.5kw motor.

Start LinuxCNC and select the Axis sim and the config loader freezes up. Pressing Cancel or the X does nothing but the max/min buttons work.
