yes it needs to be +-10VDC , a typo.. the pwm comes from the i80 yasnac controller..

Ok is that something that is already on the card and just needs to be activated? Will the other Pins retain their functions (does this only change the expansion connector)?

Thank you for the quick reply

You would need a MX4660 +7I77 firmware configuration
for the 7C81. I can make one if that's whats really desired.

You could use  7I97T firmware for a 7I85 configuration. This includes
5 additional channels worth of sserial interfaces:

Hello Everyone!
I'm new on Forum but thanks to Yours knowledge You share on forum which I'm very thankful for,  I built my own cnc machine (I'm during completing mechanical parts), but looks that software it working as it should (Z axis already built - the hardest). I'm wondering if someone built up with success configuration rpi4 + 7c81 + 7i77 + mx4660, because I want improve positioning. I'd like to not changing config of current set but only add 7i77, could someone advise me how to do that and if its working at all as it should?
Thank You in advance
Best Regards

Hello,

moving along in my retrofit I got all 3 axis, the spindle and also the 3 jog handwheels to run on my machine using a 7i97t and a 7i84d connected to the standard smart serial output. Now I want to add a 7i73 in the control panel to connect all my physical buttons and encoders on the control. For that card I need an additional smart serial channel which the standard 7i97t does not have.
I was told in an earlier post that I can edit the bitfile on the 7i97 to add rx and tx pins to the unused expansion port. I have already made an convertor board to take these signals and convert them to smart serial as shown by talla83 in this video.

to use these 2 additional channels the bitfile needs to be modified to have 4 pins on the P2 expansion connector give 2 rx and tx signals each.

My question is how to do that since the manual of the 7i97 informs me that loading wrong bitfiles will brick the card.
What steps do I need to follow?

The mist buttons use labels that change when pressed.
The spindle buttons use text that does not.
There are separate properties for each technique.

Try this:

What will be producing the PWM signal?
You can easily make a crude PWM to analog converter with a resistor and capacitor that will be good enough for testing stuff, but for 0-10V it would also need a transistor and another resistor and a 12V power from somewhere.
And just to be clear, modern and old servo drives use +-10V, not 0-10V, so that is another can of worms altogether.
VFD use 0-10V, most new-ish ones can also be programed to use 0-5V so no need for any conversion.

hal and ini file are missing a lot of required stuff, so that will not work as noted in the debug section of the error report.
Start with some basic hal and ini, then remove only the parts you do not need, might be a bit easier as you get errors as soon as you remove something important.

Good day
Wasn't sure there to post this thread, since is a bit off the Linuxcnc topic but was hoping to get some pointers at least.
problem is related to the current drive protocol that is used in the old Yaskawa cacr-ir series servopacks. it uses Rs-422 protocol with 48khz PWM modulation on the u / V phase to drive the servos. These Servopacks are becoming harder and harder to repair and to buy , prices are sky high.
Will be tapping into the wires shortly to see if I can get some readings from them , wondering if any one on this forum offers Raspery pi or similar programming / development services? Hoping to make a simple dual chanel PWM to 0-10VDC convertor. so I can use regular 0-10VDC command on more modern servopacks.
For more details see:

Thank you kindly to all..

Hello Leo

It has been a while and I've opted out of modbus and using ethercat now. This is the last backup I have found. Does this help you?

Hello everyone

I am getting the same error with a new install of LCNC 2.9.3 on amd64. (Also affects my 2.9.2 install)

Hello.
I am working on a project that involves controlling a stepper motor in linuxcnc. I wanted an ethercat configuration so I bought a TMCM-1310 from trinamic and a sanyo denki SF2424 motor. I managed to install ethercat using the instructions provided by rodw. But I am new to linuxcnc and I have no idea of how to create the .ini, .hal and ethercat-conf. My current configuration is giving me this error and I do not know how to proceed:

Hallo liebe cnc Freunde,,

ich habe noch einmal versucht meine maschine mit ease probe  zu erstellen.

Die probe_tab  maschine läuft, alle Achsen fahren, cnc programme  sind ausführbar.
Die easy probe panels sind sichtbar. Die Buttons lassen sich drücken, es passiert aber nichts.
Ich habe alles mögliche probiert, finde keine Lösung.

Viele Grüße karlhe
