writing to an eRob motor and communication consistency issues

[jennhhw]

Hello Everyone,

I am student who has recently begun working with EtherCAT and am currently working on a research project involving communication with an eRob motor using the EtherCAT protocol. However, I have encountered a few challenges that I am finding difficult to resolve.

Issue 1:
I am experiencing difficulties consistently getting the motor into Operational mode. I have been referring to the suggestions provided in a previous issue (#712) and have been testing the recommended code alongside 'simple_test'. Despite these efforts, I have been unable to achieve consistent results.

Issue 2:
On the occasions when the motor does successfully enter Operational mode, I am able to read data from the motor; however, I am unable to send write commands effectively. I have been utilizing the code referenced in issue (#712). Although the issue has been marked as closed, I am particularly interested in the comments made after its closure, which discuss approaches to writing commands to the motor.

Additional Context:
The motor in use is a ZeroErr eRob motor, which can be found here. I have been working to understand the EtherCAT protocol over the past few months and have been facing these issues for some time. The code I am testing is largely based on the final version referenced in the aforementioned issue (#712).

Any guidance or suggestions that could assist in addressing these challenges would be greatly appreciated.
