OK this explains a few things .
Here is the output of pdos command :

SM1: PhysAddr 0x1110, DefaultSize  253, ControlRegister 0x32, Enable 1

So I should change the Sync master and the 6000 something addresses .
But the IO has 9 input blocks and 7 output blocks . That seems a bit odd .

OK that's the pdo of the servo drive .
I'll correct the xml and try again .

Edit :
after reviewing the response of the ethercat pdos command everything became clear .
The only thing needing correction was the syncMaster id . After that the inputs are readable .
I tried my luck with the operator panel . All in all ok but can't seem to find the accepted data types .
halType="u32" u32, s32 and bit are accepted, but what are the 8 and 16 bit types ?

at hal side there exists only u32/s32/bit/float .

the ethercat side you have to specify with the bitlength. Lcec then handles it internal
as s or u 8,16,32 and copys the values to the halpins(32 bit size) .

OK, so the current state is this .
I have power to the drives and the Estop circuit is ok . But the drives are still reluctant to run .

 

The drive is in PREOP mode and the status word remains 0 whatever I do .
Is it possible the drive times out after a certain amount of time, or is it something to do with the clock syncronisation ?

P.S. It doesn't respond to error clear as well .

hello,

as long as the drive is in ethercat preop mode there is no cyclic pdo communication.

So, something with the ethercat configuration is still not working.
You have to look in dmesg for the error messages, with ethercat debug level set to 1.
start linuxcnc cnc, and search in dmesg for the messages after the last "ethercat: requesting Master 0" ....

seems that the slave has an fixed pdo mapping.
I think you have post the pdo config of this drive on top of page 2.
So build the ethercat_conf exactly like the readout has been.

SM2
RxPDO 0x1600 ""
PDO entry 0x6040:00, 16 bit, ""
PDO entry 0x6060:00, 8 bit, ""
RxPDO 0x1601 ""

PDO entry 0x6081:00, 32 bit, ""
RxPDO 0x1602 ""
PDO entry 0x60ff:00, 32 bit, ""

use 1600, 1601 and 1602 to get the pdos you need

Should I also set the configPdos="true" to false ?


P.S. Do you have any experience with this siitool ?
I'm hoping I can use it to write the spindle sii .

I don't know this tool. I would do this with twincat, no risk...

In the meantime i had the task to get a lot of Delta vfds working on lcec. Them SII Eeproms has been incomplete too, but i wasn't able to do a working rewrite.

So i created a way to get etherlab master working without the readout content of the SII EEprom. Now you can load a bin file (that has been created from esi xml) at bus startup, i think this will help a lot in the future.

On what Kernel you are working?
Do you have an functional esi xml of your spindle drive?

I haven't checked the kernel version .
I just installed the latest version from the site .
As for the spindle drive all I have is a portion of the xml machine configuration .
In fact there are two xmls for technosoft drives . All in all they seem to correlate with what's in the machine config file . I'll have to double check it with the pdf for that as well .
