Hi,
when I bought the B2 series servos they did not have a braked one and yet I wanted one. The Ebay company (fast-to-buy) I bought from
got one in for me, they said from Delta, maybe a warehouse, and within18 hours. I presume therefore that they deal fairly closely with Delta.
While Delta is a Taiwanese company most manufacturing is done in China

In subsequent emails with them, they now always try to tell me about their latest special....., they claim that on the basis of Delta sale volumes in the
previous year that they had been offered a better discount and they want to pass (some) of that on to me, presumably to induce me to buy more of them.

For example I paid $438USD (excluding shipping) for a 400W B2 series servo/drive and cables in August last year. They offered me the exact same
model servo/drive and cables for $387USD just before the COVID thing blew up.

I cannot, to my knowledge, buy direct from Delta, but I suspect the company I deal with is reasonably close to the source and all factory brand new
with Delta warranty cards etc.

I have done a little research and found that Schnieder Electrical offer a plugin module that allows their LUMIEX32 servo drive to become dual
sensing. Allen Bradley KINETIX 5700 drives also offer dual sensing.

I rather suspect that dual sensing and that loop being closed at the drive is more widespread than you imagine.
