Tench wrote:Been and made some adjustments,,
My throttle min output voltage is 0.85v so i set the min input to 0.87v
max input displayed by the CA is 4.19 so i set this to 4.10v
Min out put is set to 1.40v as i know the controller does not start til just above this voltage (even tried stting this to 0.40v)
Max out put is set to 4.10v.
Ramp up set to 500, ramp down to 999.

Exactly - you need that connection.
Your Vo level in your last post confuses me, but I'm just hacking this along with everyone else, so there may be other parameter interactions in play we haven't quite figured out yet that will explain the different Vo behavior between your unit and mine - it will all become clear soon I'm sure .
Anyhow - make the throttle connection and see how it goes.

Would it be possible to measure and display the current motor efficiency as a percentage?
I guess it would rely on the motor load being readable in some way.
I have no idea if it's technically possible, but thought it would be a nice feature if it is.

Tench wrote:Another thing i noticed is when set to current throttle, with the drive wheel off the floor if i open the throttle just a little to get the wheel spinning the throttle output voltage generated by the CA (on the 2 click left screen) will climb untill it reaches the preset max figure while the throttle imput voltage is still near to minimum, can someone else try this to see if it is just my unit?
But i love it!! the fine control of the throttle parameters and adjustable ramp up has ironed out the abruptness it had before and made me very glad i got one When Justin has got all the bugs out i shall have another for my next build!
toolman2 wrote:but the good news is that its a massive improvement in throttle control and is really badly needed on a geared motor like yours, i might just add a quick told you so if you dont mind tench and now with justins fine work and some fine tuning, we can all maintain way better control of our increasingly powerful 'flip you off the back cos the throttles so touchy' type machines.
i reckon lukes agni bike vid (the you know the bike is dangerous one) with the poor dude laying down behind the bike shoeless, would have been a lovely and peaceful bicycle ride if it had a well tuned current throttle..
