It doesn't matter if he sets it to torque mode. I think we're trying to solve a problem that isn't really a problem. They're both driving one shaft so it'l work just fine without any slip if he sets to torque mode.

The problem with speed, is that it'l oscillate. You can't get it exact, and the controller will try to limit speed and the other is trying to speed up. They'll fight eachother.

I'm still not sure why he's using 2 motors and 1 shaft and not just one larger motor with larger controller.

Medzs, have you built this yet?

want to start a new thread on your build?

Using a single pot for both controllers sounds a lot easier.

Well yea its a single pot going to two controllers but if one is off a little you just add a little resistance to the other to balance, so another pot in series for adjustment or calibration to make them the same

How about a pic chip looking at current in both motors and controlling input to both controllers from the pot

I tried one pot, but didn't work...

I don't calculate with torque mode, thanks I will try.

I use 2 motors and controllers because this is a boat, bigger motor means bigger Volts, with 48V system I can get easier boat license. On the other hand when I would like go slow one motor is enought, when I need more speed I turn on other motor also. This is a theory now. I hope on end of next week I can make first try with boat.

Bigger motor does not necessarily mean higher voltage.

It looks like that I am OEM with deeo pocket. I get answer for my email. Shortly: If I buy 1314 Prog. Station, The WinVCL and full documentation is FREE....

I've been trying for over a year now.

How much is the programming kit?

I think he may have misunderstood. I thought the Programming station was just the software that we found and the connector, I'm pretty sure that's all that Tomofreno on DIY got for his $400 something purchase.
