Unbalanced """s
should be idx="0", not idx=0"

It's this parameter Normally set it in the hal file.
The  unit is encoder increments/measurement unit.

Based on modbus specification in this inverter manual I wrote a python program to steer vfd. Things so far I did (maybe useful for someone) :
1)connect Huanyang FC01 to 485-usb and then to rpi4 with linuxcnc
2)set jumper 4 to On on vfd to enable communication
3)program vfd:
P00.01 = 2
P00.06 = 8
P00.07 = 1
P00.09 = 0
P14.00 = 1
P14.01 = 3
P14.02 = 0
4)start my vfd_monitor

After those steps I was able to connect successfully and drive my spindle.

Next step will be to integrate it somehow with linuxcnc

the linebreak was a copy paste error. still same error message

Dear all, 

I would like to interface custom hardware with AD5362 (8ch DAC), via SPI interface. Would that be possible and what would be the easiest to hook this up?
I see BSPI and SSI interface is available in HM2, but do not understand whether they support custom SPI protocols. 
How is this done in 7i77 and can one adapt it for custom hardware? 

Thank you!

On the lower panel one of the icons is search, although it maybe just be an application search, either way it's quite easy to customise, right clicking on a panel allows you to add, delete or modify icons.

# EtherCat
loadusr -W lcec_conf /home/bf20/linuxcnc/configs/sim.axis/ethercat-conf.xml
loadrt lcec
add lcec.read-all servo-thread

add lcec.write-all servo-thread
net mon halui.machine.on lcec.0.EL1014.din-2
net mon halui.machine.off lcec.0.EL1014.din-3

My thought of testing the system with an Orient command, I understand now was very naïve.
From others examples, introducing this ability requires pretty much a total tear up of the whole spindle control setup, and a need to get into the ladder world not just a reroute of the enable signal, and that's a move way too far way from any comfort zone for me.
Ducking this piece of implementation brings me much relief.

Thanks for your effort to help.

Changing the IRQ coalesce settings does improve the ping times noticeably on Intel hardware,
but your 4-5 ms  peak ping time indicates other issues, likely related to power management.

My system with Intel MAC and default IRQ coalesce settings:

PING 10.10.10.10 (10.10.10.10) 56(84) bytes of data.
64 bytes from 10.10.10.10: icmp_seq=1 ttl=64 time=0.316 ms
64 bytes from 10.10.10.10: icmp_seq=2 ttl=64 time=0.250 ms

64 bytes from 10.10.10.10: icmp_seq=4 ttl=64 time=0.250 ms

Same system with IRQ coalecing off:

Have you disabled all power management in the system BIOS and grub?

Have you set isolcpus to the last CPU in the grub file?

Do you have idle=poll in the grub file as well?

(These are basic latency reducing steps for any LinuxCNC host)

I finally insalled my ethercat master. and when running "ethercat slaves"
I see my beckhoff devices:
So next I created a standard axis-sym conf
I modified the axis.ini by adding a new halfile:
This is my ethercat.hal:
and here is my xml file:
when starting linuxcnc I get this error message: which does not really help me to figure out what is wrong. My guess is that I did something wrong in the xml, but I can not figure out what.

Thanks for your help.

Hi,
I am also working with the A6 servos.
I purchased the Stepperonline 750W sto for testing purposes. I got everything up and running without any problems.
But I have a few questions:
How can I adjust the electronic gear?
Is there a function in the .ini file or do I have to set this in the servo driver?
My axis has a pitch of 50:1 and the gearbox in front of it is 6:1.

Which signals are used in the cia402_homecomp?
Are the home switch and the Z-index of the servo used here, or just the home switch

regards
