Bus Shift Mode or Master Shift Mode

Eddie,

generally you should direct questions on the SSC to Beckhoff or ETG. Now I am not sure what you mean with Master Shift Mode... Any more details here? Can you refer to a section in ETG specs? Only then we can answer if this is PRU-ICSS related or not.

Regards.

Hi Frank,

I also post the same question in ETG forum. 

We now use the Acontis Master protocol + RTX to communicate with our developing TI-based slave. The master supports the Bus Shift Mode and Master Shift Mode. We now use the Bus shift mode to communicate with Yaskawa servo driver and TI-Based slave. The Yaskawa servo driver NEED to be set a parameter for different shift mode to prevent the DC "out of sync". Our customer ask us if the TI-based slave has to do the same setting.

Sir,

I can not find the DCM Bus shift mode and DCM Master shift mode in ETG spec.

But, the data can be got from  http://www.acontis.com/eng/products/ethercat/ec-master/fp-master-synchronisation.php.

The Yaskawa servor driver has the CoE object 0x2767 to config the DC Control Loop Mode. It use the Hilsher as its EtherCAT slave solution.

Our customer ask us how to set for TI-Based slave.

Best Regards,

Eddie

Eddie,

reading through yur link this is a master option. You may also ask Acontis for help:

>>Based on our experience we will advise customers concerning the right method to use for their given application and hardware.

The TI slave will just sync to a DC master (or maybe the DC master itself if first slave in chain).

Regards.
