Hi, does that mean we should turn off slow ABS current to false for safer use on high phase amps
SLOW ABS should not be used. You can also try to lower the Time constant T to 500uS.
Then press Calc Apply Old and write the new values.
The word “safer” is ambiguous. Safer for whom/what? In which ways?
There are some who prioritize controller breakage (or cost) as top priority and some who prioritize human safety as top priority. There is also a chance controller breakage can affect human safety. So this is an interconnected web.
An example would be: controller freaking out being “too safe” (for itself) and cutting the brakes or throttle at a critical moment, causing a wreck and human injury. But the controller is safe. Another example would be: you got a little too demanding on the controls and the controller shut off instead of frying itself, which meant that when it kicked back on, you were able to safely slow to a stop and avoid a crash. But more likely in my experience is that when the controller “kicks off” it causes a loss-of-balance event for the rider that sometimes is unrecoverable.
So there is no clear cut explanation of what is “safer use” aside from just turning the maximum current levels (not the Absolute Maximum Current trip point) down a lot. And even that has times when it’s not “safer”.
Understanding what each setting does and what you want your machine to do in various situations is the key.
Also, use hardware from a vendor that submits their settings to the VESC software project. If vendors aren’t doing this, maybe consider avoiding them instead of borrowing settings for other hardware. Using the settings that come from the hardware designer seems like a prudent move. If those are absent, switch vendors.
For my use example, it is for a Surron and not wanting to trigger a fault and at the same time not wanting to blow up a vesc
