Hi Jun,
thanks for your answer.
>well, can you specify the meaning of "can't read/write RxPDOS"?
I change value with usb cable for example, i enable the driver and the
Control_World value change and i enter 500 in torque value. The motor
turn...
I try to read Control_World via ethercat. It always stay to 0x00 and i
try to enter 0 in torque register via ethercat to stop the motor and
the value never change and stay to 500...
It's why i say that i can't read or write RxPDOS.
With TXPDOS, i have the same value with ethercat and via USB interface.
And i don't understand why...
>So you know how to write a RXPDO. Everything look fine. I didn't see
you write any other RxPDOs, so why did you say you can't read/write
them? Where is exactly the problem?
Yes, i think i understand how to write or read RXPDO but my code have no
effect on the driver's register... I have no error but nothing happen... :(
I hoped to have been more clear about my problem
Best regards,
Oliver Tempier

Hi Olivier,

in your code, you read the EPOS3_0_Control_Word, which shows 0x00. It
looks fine, as you didnot set the value to anything else. So you CAN
read RxPDO EPOS3_0_Control_Word. And by default it is 0x00. What did
you expect?
printk(KERN_INFO PFX
"RxPDOs*********************************************************************
\n");
status=EC_READ_U16(domain1_pd + EPOS3_0_Control_Word);
printk(KERN_INFO PFX "Robotics => Cyclic_task=>EPOS3_0 Control Word = %d
\n",status);
And you've tried to set EPOS3_0_Target_Torque to 0,
EC_WRITE_S16(domain1_pd + EPOS3_0_Target_Torque,0);
So you know how to write a RXPDO. Everything look fine. I didn't see
you write any other RxPDOs, so why did you say you can't read/write
them? Where is exactly the problem?
Best Regards,
Jun

Hello,
I try to use an maxon EPOS3 driver with igh ethercat library.
I wrote a test code in c, all seems ok. I don't see any message
error in debug file.
But i can't read/write RxPDOS and i don't see why... I have no
problem to read TXPDOs...
I join debug file and my source file.
I'm on this problem for a week, i'm starting to go crazy :p
Please, If someone could help me?
Regards
Oliver TEMPIER
