MBL1660A - closed loop speed mode for sensorless control

After the discussion with Gabriel_Isko in another topic:

www.roboteq.com/index.php/support/forum-...s-no-feedback-signal

Really hope the sensorless control can support the closed loop speed mode, which is technically not complicated to do.

Thanks in advance

It can in our current firmware release, but you need a form of position feedback. You will need to use an encoder.

Yeah....but the desired feature is : sensorless close loop speed control WITHOUT any encoder.

This is very interesting for PURE sensorless application, and in my opinion, this is not difficult to realize in current Roboteq driver like MBL1660a, only a tiny modification should be done in the control software...

As i mentioned lots of times, the speed/position feedback can be given by sensorless technique without any problem.

If u want, here is a exemple of commercial driver which can do this, and there is a lot of similar products :

I give my suggestion here just because i was happy with roboteq and really hope you can do better. So plz stop repeat your answer and discuss with your technical guys if u can't get my point...
