Exactly, yes I can use higher voltage. I'm testing 8kw motor at 66v with a gen4-6.
Will turning peak amps down to s4 levels be a good simulation of using s4?
Can run at 96v nominal.
I'm getting a price of some surplus gen4-s4 80v from Spain. Need to know if they will work first.
I could use about 20 controllers if someone finds a source.
Thank you again!

Any one encountered with
0x4F54 AUTOZERO RANGE ERROR
Is it a hardware malfunction ?

Yes it is a hardware fault relating to the current sensors.
