For anyone interested XPD have also added a description of the KH6XX (sinewave) protocol HERE.

So, it's official now: XPD supports programming for sinewave controllers we sell. That means you have yet another option to program your controller using a better quality software compared to native configurator. That means also you can use multiple platforms other than Windows. That includes Macs and other *nix type of systems or anything that can run Python.

New version of XPD can be downloaded here:
https://sourceforge.net/p/xpd-ebike/cod ... ree/trunk/
OK so I know you said it was better quality software, but it seems to have less scalabilty for the functions I need, not more. The software you gave, allows me more fine control over regen whereas this has only 3 settings. I see that block time settings are tweakable but I always leave at 1 second so irrelevant to me.
What board do we select 4 sinewave? regular 218? are all voltage settings r12 mod friendly (like the android app,) or still skewed? Do you perhaps have recommended settings for XPD that work well for us to try, or do we just experiment?
Still very good news :D the more variety of options the merrier I guess :wink:

They still have block time variable? I would set that to zero in all cases. Telling the software to ignore the phase current at launch can lead to such high currents that the FETs fail. I blew one 24 FET controller 5 times with a low impedance high current battery and a Cromotor. Super high phase currents also generate a lot of motor heat. They do make fun thrust, but choosing a reasonable phase current should give adequate thrust.

If folks still want a "high thrust launch" which is what block time is for, there should be a separate phase current setting for it, other than "whatever the battery can deliver and the motor can take" which could be more than the FETs can handle. Or perhaps there is such a limit programmed into the controller already, and that is what is used during block time. If so, then it is already covered.

Yes. Block time set anything else but ZERO is a controller killer.

That's good to know. I've never paid too much attention to this setting but have now disabled it completely and hid in the smartphone interface, so it's not programmable anymore.

Interesting though, I've seen another definition for Block time. Something like this:
BlockTime: The amount of time to try rolling the wheel before deciding that it has been blocked (e.g. if the Hall sensors signals won’t change for that much time, the controller will stop trying).

I guess that's wrong?

your explanation may be correct. at least it sounds logical, that the naming comes from "blocking the wheel".
basically setting it to a specific values, disables the set current limit for the set time. so your battery and/or the installed FETs are the limit. and if your battery is powerful enough (and not limited by eg a CA) it will allow the FETs to suck all the current they can from the battery. and this MAY be too much for them. and you will receive some dead units for repair :(
unfortunately this block time thing makes your controller look very powerful. it gives a very snappy start from a standstill. this boost is only there for a fraction of a second (or up to several seconds), but as these electronics blow within milliseconds it can be way too long.
maybe try it out yourself?! and better to keep it set to 0 by default, and make this a "void waranty" feature (if you can include that in the firmware, like some kind of software fuse).

Perhaps the manufacturer should answer the question and define the parameter.

Should be easy to verify what it really is - current overshoot or hall detection delay. I'll test over the weekend and post results.

Hey, I have the 12fet controller. Where can I download the programming software?

Anyone have a quick color wiring chart for this controller ? I can guess most be could be a good sticky for this controller.

What kind of switch is needed for the cruise activation wire? Do you sell one?

There are labelled tubes on the wires denoting the connector on my 12 FET. Nice marking.

Color codes for the individual connectors would be good, are they the same as some other controllers that we already use, perhaps?

Wire colors are very much similar to Xie Chang family of controllers with just slight variations.

all wiring is super easy to identify even without marking just by looking at the connectors. Well, if you dealt with controllers before.
Five pin hall sensor connector is self explanatory, as well as battery and phase wires.

What's left is a throttle 3 pin (black, blue, green), a two-pin ebrake (blue with white stripe, black), cruise (solid blue, black), three pin 3 speed connector (black, black, gray).

Optional can be two other connectors for alarm: two-pin power - black and red (gotta be careful with these as they supply pack voltage, not 5v), and alarm signal (orange, brown and pink).
Single purple wire is a high ebrake that can be used instead of regular ebrake to enable stop lights as it is shorted to battery positive instead of ground like in case with low ebrake (EBS-).

That's pretty much it.
