In my setup I am trying to use a couple of EL7041-0052 (the EL7041 variant without terminals for an encoder) to run stepper motors without feedback. When using the softmotion drivers for the EL7041 (Rev22 and Rev24, even selecting external feedback type doesn't work) the device log shows warnings for the corresponding hardware: "SDO write error 0x1 -> 0x8012:0x08 eError 0x1 AbortCode 0x6090011".
0x8012:0x08 is the register for the Feedback Type. My best guess was setting the the register value in the start parameters to zero, but the result is the same.
What else can I try to get the hardware to work? I have screenshots attatched showing the running fieldbus and the log messages.
EDIT:
One clarification: the "device log" that shows the error is the PLC, not the ethercat terminal. The log of the terminal itself shows neither errors nor warnings.
I let this project rest for a while and picked it up last week. I have been in contact with the support from beckhoff and got the information that the terminals were identical (communication wise).
As the Log of the Axis (not the drive's log) shows the error when trying to write into the register 0x8012 and set the value for an encoder to a value that is the default - at least according to the manual - I was wondering if it is possible to "not write that value" to skip that part? Or am I misunderstanding the way the library communicates with the drive?
