If you bought the motor and Votol from Siaecosys they should have paired it before shipping. Only thing you need to change are things you didn’t tell them when you bought it.

So far all the Votol configuration files ive seen are 9960 phase current, so probably should leave that alone.

For the drivetrain slop settings:
“Starting torque” is the initial torque until drivetrain slack is removed. Normally set to 0
“Combinative torque” is the torque after drivetrain slack is taken up. Normally set to 0
“Rate of rise” is the slope of increasing torque, max is 250.
“Rate of decline” slope of decreasing torque. Set 100 to 250.

My experience with this setting is it always feels like it has some soft start built in, even with soft start off and rate of rise at 250.

For flux weakening, i have hub motor so it doesn’t use compensation value and I set flux weakening to 0. But for your ATV, 5.6:1 reduction, you probably want flux weakening. I believe they advise to start low and test drive, add 100 then test drive, add 100 then test drive, until you get the best performance.
