Cycle Analyst current throttle

[veloman]

I am attempting to follow the wiring in the manual (version 2.1 section 9.3) to make a current throttle. Apparently one of my connections is bad and is causing WOT. But my question is, is this functionality worth it? Does it work okay? I know there is some much more advanced wiring plans floating around on ES on how to make a current throttle, and was wondering if this route is a viable alternative.

But damn, I went crazy trying to solder those tiny connections on the CA....

Not sure if it applies to your model but in V2.3 Users guide there is this statement which is not in the 2.1 manual :
"Note that it is essential to set the AuxVoltage input (see ) to either the current or speed limit first, otherwise the system will take off at full power when turned on"

Thanks for that info Steve. I set the aux voltage to amp limit, and I've made progress. It still turns the motor on when I turn on the controller, but only for a second, then it rests like normal. I probably have to play with the throttle settings more.

Update: I just rode it, it does still sputter a bit when stopped. It does work okay, but it's definitely not as responsive, with a lag time. My speed setting 1 is set to 55%, yet I still pull about 80% power during acceleration with it WOT.

Overall, I'm probably going to go back to the normal speed throttle which lets it run much smoother. I've gotten pretty good at twisting the throttle very slowly to keep power limited when desired.

Rode it 5 miles today, and think it's good for easy riding, but it's not as much fun and doesn't have the 'kick' of the speed throttle. It has the possibility of keeping the motor cooler (much easier to control the high wattage), but I am not certain of that yet. I ended up swapping my wires and rode home on the speed throttle. Like I said I may need to adjust the settings to perfect. Will look into it.

If you run >3kw, I'm sure it would be a lot more useful, but at 1300w, I'm not sure.
