Brake rpm minimum

Hello

 

I have been using the adc1 throttle in current, no reverse, brake centre and having the centre as 0

Having a couple of one way cluthes in the system means I cannot regen and if not using the drive it is best for the chain to stop.

The issue being that with the controller in this configuration it makes some noise from the motor at times and I believe causes extra power usage when vehicle is idle

I cannot find any way to disable braking below an rpm?

It seems like a fine feature to implement, it could look something like min brake rpm forward, min brake rpm reverse

I'm not sure max brake rpm would ever be useful, but maybe for someone.

 

Fine product you have here, many thanks for your work :)

The audible noise issue was because I had disturbed the shielding for some of my wires Though it doesn't totally address the issue as I still think there is unnecessary power drain at motor idle.

I still see some oscillations from encoder feedback at 0rpm but only +/-.2 degrees (as5047p 3.3v spi with all the pull ups and pull downs required, and one more to help the fall time on one pin i don't remember)

I still think the minimum brake rpm or a brake fade rpm would be a useful parameter as I've seen in Cascadia drives..
