Homing to hard stop with Delta B3A drives

[carboncymbal]

Is it possible to initiate the various homing procedures in the delta B3A drives? Specifically, is it possible to home to the physical hard stop?

I do not believe it will be easy to make it work that way unless you can figure out how to switch the drive from PR mode to communication mode and then power cycle it. As far as I am aware, we do not implement any kind of EtherCAT commanded homing in the Hickory.

Do you have the multiturn absolute encoders? With those, you should only need to home once after setting up the machine and after that only when the encoder battery is replaced or if there are physical changes to the machine.

why would you want to do that? with absolute encoders you "home" once every ten years

In my case I didn’t purchase the absolute encoders. I had originally intended to use them with acorn, and selected this drive not for ethercat functionality, but for step/dir with STO functionality. In hind sight, I wish I had purchased with absolute encoders for the option ti use all that hickory can offer.

That makes it difficult to recommend any particular method. I don't think it is possible to switch from PR mode to Communication mode without a power cycle. It might be worth reaching out to Delta's customer support for your region.

Also, I will bring up adding support for EtherCAT homing modes to the future Hickory firmware changes discussion.

we no plans to support home to hard stop with Hickory, use absolute encoders which are a requirement for Hickory.

the delta drive with absolute encoder motors will also accept step and direction they are not exclusive features.
