vesc throttle response

Hi,

hope someone can help.

im setting up a vesc 60100hp on a bosch gen4 mid motor (No sensors. driver board removed)

The motor detection works fine , as does the throttle detection (chinese ebike hall sensor type)

the throttle is mapping at 2.5v max input. Using the 3.3v not 5v

however the motor starts at approx 15% and is full speed at 20% .

its practically an on off switch, although there is a ramp if your really careful rolling on.

this is the second vesc ive tried and both reacted the same.

I have also tried both a 1k and a10k across the adc1 to ground to stop it from floating.

Any Ideas?

regards

Tony

If you use control type "current" thats normal behaviour if you have no load. You control current and not rpm by applying throttle input.

It makes no sense running an ebike other than current control.

Cheers, so i kind of get it now, its the same as with an ic engine you need the load otherwise the rpm will rise immediately upon pressure on the throttle. I am going to set the bike up on a turbo trainer  to do the initial setup. Is there a good resource for me to study, as to what adjustments to make to effect the throttle behaviour?
