Hello, I think I have a hardware cutoff on my 75100 v2 pro aluminum ; I’m getting cutoffs on peak currents that should be adding 160 amps, despite the absolute maximum current being set to 190 amps. On my old setup, I solved the problem when I found a parameter distribution that gave me a maximum peak current of 144 amps, but I can’t seem to get that on my new one. Any ideas? My current parameters are: battery current 65 amps, motor current 190 amps with an ABS limit of 95%.
Thank you
Not sure what you mean with ABS limit 95%
In my experience the ABS MAX current should be 1.5x the max motor current for reliable operation
Yes I am agrée with you , but it seems that the causes of my cutoff are the peaks over 150 amp ;
I had that thing with my last set up too ; everything was ok when the peaks were not over 150 amp
For the 95% , it is my maximum scale current , but i am agrée this value don’t have any sensé
I am gonna try to put absolute max at 180 amp with slow abs current l limit enable and max current scale at 83%
But if you have other idea …
Why would you lower the scale percentage? As it says in the VESC tool, the scale percentage is ONLY to enable lowering the abs max parameter while keeping the old, higher value for reference.
Can you please screenshot your parameters? Right now, what you told us is:
Max battery current: 65 amps
Motor current: UNKNOWN (you said motor current but you meant abs max)
Abs max: 190 amps (real value 190 * 95% = 180 amps)
Abs max scaling: 95% (this should be 100% and just change the abs max directly)
My motor current is 120amp, my hypothesis is :there is an hardware cutoff over 150 amp with the 75100 so I am looking for parameters that allow me to avoid peaks that exceed 150 amps.
I cannot set an absolute max current of 150 amps because I want to keep the motor current at 120 amps.
So, I set the absolute maximum to 180 amps and I adjust the maximum scale to achieve peaks below 150 amps.
Wrong idea ?
