ASD-A2 EtherCAT on LinuxCNC

@chimeno
Does not matter. I've been testing all week. See above.
I'm done setting 10.png. But I will make a few more changes according to you.

the speed control problem that you first have to adjust in the drive configuration so that it works at the speed and acceleration you need in the machine and then finish adjusting in linuxcnc

Do you mean "MAX_ACCELERATION", "MAX_OUTPUT" and "MAX_VELOCITY"?
"MAX_ACCELERATION" is parameter P1-34 and P1-35 for ASD-A2. But I don't know how to convert "MAX_ACCELERATION = 1500" to "ms" for ASD-A2?
And which ASD-A2 parameter corresponds to "MAX_OUTPUT = 30000" and "MAX_VELOCITY = 200"? P1-40 or P1-55?
I apologize for the large number of questions.
Thank you very much and have a nice day.

The big bugs in this picture are thanks to .COMP where I had "950 0.020 -0.030" set. After adjusting to "950 0.020 0.020" it is no longer a problem.

Hi @jirkam,
I'm glad it worked well for you!

The big bugs in this picture are thanks to .COMP where I had "950 0.020 -0.030" set. After adjusting to "950 0.020 0.020" it is no longer a problem.

what do you mean .COMP ??

And which ASD-A2 parameter corresponds to "MAX_OUTPUT = 30000" and "MAX_VELOCITY = 200"? P1-40 or P1-55?

this parameter is marked by the scale in driver and motor, you have, the fixed scale is 0.1 rpm and a motor at 3,000 rpm, so I think 3000x0.1 = 300, it seems to me that the scale has to be "300"
MAX_OUTPUT = 300
MAX_VELOCITY = 300

MAX_ACCELERATION" is parameter P1-34 and P1-35 for ASD-A2. But I don't know how to convert "MAX_ACCELERATION = 1500" to "ms" for ASD-A2?

The acceleration values ​​depend a lot on the type of structure to move, the value to put P1-34 / 35 is the time you want it to take to go from 0 to 3000rpm,
In linuxcnc it is in units per machine over your maximum speed of 300.


I usually use the drive display to indicate the actual motor speed, I think you can configure it with parameter P0-02 value 7

Hi @chimeno
.COMP I mean in .ini / [AXIS] / COMP_FILE.

I will try to set MAX_OUTPUT = 300 and MAX_VELOCITY = 300.
Last time you wrote:
"setp lcec.0.x.srv-velo-cmd 30000" and "MAX_OUTPUT = 30000"
I'll try and see what happens.

Due to the poor design of the machine, I would like to use the maximum acceleration "MAX_ACCELERATION = 500" and "MAX_VELOCITY = 300".
What value corresponds to this setting for P1-34 and P1-35?
500ms? Probably not? Or yes?

I will also set parameter P0-02 to 7.

Thank you very much. Jirka

Hi @Jirkam,

Ok, thanks

I will try to set MAX_OUTPUT = 300 and MAX_VELOCITY = 300.

Sorry I think it looks bad, one way to check it is to use the settings on the drive screen to see the engine speed and with this signal you should see 1500rpm "then the scale is correct

Due to the poor design of the machine, I would like to use the maximum acceleration "MAX_ACCELERATION = 500" and "MAX_VELOCITY = 300".
What value corresponds to this setting for P1-34 and P1-35?
500ms? Probably not? Or yes?

It can be, it depends a lot on the machine,


You can also adjust the parameters automatically through the WINDOWS program that includes the "3.2 Auto Gain Tuning", which allows you to do many tests to see what is the maximum you can go.

Hi @Chimeno

If I understood this well, I found out by testing that the servo speed is 800 rpm on the display (set parameter P0-02 = 7) at a speed of 12,000 mm / min in Lcnc.
The servo speed on the display is 1,200 rpm at 18,000 mm / min in Lcnc.

It's different than I thought.
I'm starting to get lost in it.

I was just trying:
I removed "setp lcec.0.x.srv-velo-cmd 10000" and tested how low I could get with "MAX_OUTPUT".
At speeds of 12,000 mm / min I could drop to "MAX_OUTPUT = 14".
And at speeds of 18,000 mm / min I dropped to "MAX_OUTPUT = 21"
In both cases, the system behaved the same as with "MAX_OUTPUT = 30000"

Is it possible to observe anything from this?

Thank you Jirka
