Can larger BLDC motors be controlled with VESC?

Hello all,
my intention was to control 2 BLDC motors with VESC6 MKIII (one each). The electrical values of these motors are within the VESC's rage (48 V, 80 A max), but they weigh 7.8 kg. Starting the VESC Tool FOC wizard the heaviest motors mentioned there are about 2 kg. And at the screen occures a warning not to choose a wrong weight - this could destroy the motor.
Is the VESC able to control my motor? (HPM3000L, 48V, Goldenmotor.com)
Gruß, Günter

I think choosing a wizard higher weight than your actual motor would be dangerous because the VESC could push too much current in the windings during parameters autodetection.

Alternately, instead of using the wizard, you could set the parameters and do the autodetection manually (setting the current and RPM you wish).

7.8kg is not a large motor but you should be fine with the wizard and selecting the largest inrunner.

Thank you. The motor is meanwhile running. There is a lot of questions remaining. Before asking I've to sort them.
