OK. I am using Prelim6. I am also using current mode for my throttle in. I actually removed the usb port to clean up the wiring. I will have to resolder it and then send you the hex file in a couple of days. I am glad to hear that this is not normal for the CA. Hopefully we can figure out what is going on with mine.justin_le wrote:That is strange, it should ramp up exactly the same way (based on your FastRamp V/sec setting) regardless of whether you release the ebrake with the throttle on or just suddenly twist the throttle. To doublecheck I just confirmed this with the Prelim6 and the more recent Prelim9 firmware in all the main throttle modes (pass-thru, amps, and watts). And after releasing the ebrake the output voltage would jump from 0V to 1V (the min output voltage) and then ramp up steadily to 3.6V, full throttle. It never went from 0 to full instantly.jdevo2004 wrote: Hi Justin. I was just out in my garage checking everything over. The brake cut off is going to the CA, not the controller. I own a CA3. I was checking the throttle out voltage to the controller. If I quickly go full throttle with my twist grip, the throttle voltage slowly goes from 1.3 volts to 3.25 volts which is normal. When I touch the brakes the throttle out voltage goes to 0 volts. When I let go of my brakes while still having the throttle at full the voltage goes from 0 to 3.25 volts instantly. What is missing is the nice controlled ramp up to 3.25 volts.
Could you let me know what firmware version you have, and if it's the Prelim6 or later could you use the CA setup utility to save your settings to a .hex file post that here? Or just list your main throttle input and throttle output settings. The behavior that you are describing is certainly not what it's supposed to be.
If it helps any, I puchased my CA3 from EM3EV.
