Hi, I am just on the way to start my ethercat adventure.
I received my ethercat servos and some beckhoff ethercat interfaces as well.
Now i recognize that I still need something to control my Optidrive E3 VFD over modbus.
Can I use the El6001 Serial Interface or wich Interface do I need?

I would really appreciate any help or hint

best Kai

Hi,

i think you need to update local git clone first. It needs latest updates.

Then build_cmake.

It is capable to switch between the two modes but it is not a 'normal' setup.

Because there are different setups there isn't a 'one size fits all' solution to do this.
In your case I would wire the DC drive as the spindle and the servo as a rotary axis (eg 'C').
Solutions will largely depend on what kind of encoder signal(s) you have and whether those track spindle position at all times or only in either turning or milling modes.
If you have encoder and index feedback from the same source and the encoder position isn't lost when operating the the spindle at max speed then you can home the rotary on startup and don't need to rehome when switching from turning to milling. There is 'caxis.comp' to prevent the spindle unwinding the accumulated rotations for this case. The original version of this can be found in the zip folder in this thread:
forum.linuxcnc.org/10-advanced-configura...ling?start=50#288345

If you do need to rehome the rotary due to lost encoder position then make sure to take note of the bug described in this thread and the workaround presented:

Are you Chinese? If yes, add me on QQ: 304394405

why not use the native driver

Hi,
I´ve got a lathe with a DC Spindle drive that has an extra servo driver for milling operations. So the spindel would work as servo driven axis, let´s call it C-Axis. Simoreg 6RA26.
I´m not at that part yet, but i´d like to know before i start working on it, what´s best practice to implement that.
I´d like to have the spindel working as spindle with +-10V for RPM as a normal lathe and in milling mode it should switch to the servo driver, that works with +-10V too. I think i have a closed loop there too. Should i wire them up as if i had one physical spindle and one physical servo ?
So is Linux capable of switching mid program between the two modes ? is that a normal setup ?

Do you mean the hal_inertia_factor parameter?
Sorry, but I can't find this parameter (neither in halshow nor in the source code).

"Also, the program execution time should be faster."
Are you suggesting lowering this value: SERVO_PERIOD = 1000000,
or this one:
[TASK]
TASK = milltask
CYCLE_TIME = 0.001
I performed the above-mentioned tests with these settings.
 

When I was testing this signal input, I found that when I turned on LED0, the corresponding IO PIN was lit up at pin number 16. Similarly, the output position was also the same. In summary, the data I currently receive has been shifted by 16 bits. Additionally, I have attached my XML and the test results from Beckhoff (they are all OK). Could someone kind-hearted please tell me why?



Changed to a different model of the product. This model does not fit the IGHmaster.

I guess ChatGPT looked at this thread to come to that answer.
I read more than half of this thread yesterday. Some 8 pages or so in there are many working configurations, and people with success.

@John,

Maybe that's the case, but this is solvable.

I am writing some new code. We are free to change the state machine transitions for Lichuan.
Here you can see how to set states. In fact it's just a matter off setting a combination off bits in a sequence.

Currently i am waiting for a new servo drive, so my code is halted. I dont have a Lichuan here, so i can not write code for it
to solve any problems.
