I think you should ask in a separate thread, it's offtopic in this one and you'd get better help.

This is phase current setting. It's at max setting now.

Looks like it's for programming complete parameter files into controller, if you need to reflash due to bad settings or if you program large numbers of controllers for OEM delivery etc

In general (this setting doesn't work on my controller):
setting is mapping your throttle working range to controller.
If you set too high start voltage there will be a large deadband before motor starts
If you set too high end voltage you will lose some of the speed/torque as you never reach full throttle.
(5V set on a hall throttle would work like this)
If you set undervoltage too high or overvoltage too low then controller will fault. There must be margin to the normal operating voltages of your throttle.

You can play with flux weakening setting to get a bit more speed. It's described in the manual.

No, don't change them. They are correct.

Just for information,
my IveCar Electrical scooter has as standard a VOTOL EM-100 controller.
Best regards
Keld

It is interesting to me that with my controller, whatever settings I make, I cannot raise speeds more than 569 rpm. There are two situations.
1st. The controller must be limited to a factory in Germany up to 45km
2st. The Bosch motor should be designed so that at 72 volts it does not exceed 45-50 km.
This is where the question comes from. What if I put in another battery or two and raise the voltage between 84-96 volts?
Any ideas?
Something will be damaged or?
Most likely, but I don't know what will damage the controller or motor.

You should ask about motor in a separate thread. It's offtopic.
Only thing left to try in controller settings is flux weakening.
Follow manual.. Set 34 at "compensation" and 1500 at "high flux weakening value" on both places.
It could (maybe) give you a little bit more speed.

Yes, the field can demagnetize your magnets if it is too strong. Keep within limits.
If you raise voltage you'll get proportionally higher speed. The motor will be fine.
Controller can be damaged if you have a 72V controller. 96V is probably too high for the mosfets and caps to have any safety margin
