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.

cheers is there a way of controlling rpm rather than currant?

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?

You can select current control, duty cycle control, and PID control.
Duty cycle control is a whole lot more precise, in my experience. However, it seems to have full speed problems (it becomes very bouncy and unstable closer to 70% duty cycle and above).
Current control is smooth and didn't have speed problems, but it creeps up a little at a time and seems very lagging in response.
I tried PID as well, but my experience is that it only gets me about 25% throttle and I'm not sure how to adjust it using just the BT connection. I see it on the laptop, but I'm primarily using my phone to interface with the controller.
