Setting the speed and torque
You can modify the parameters of the file if you don't want to use the default
file settings.
In the Endodontics function, the speed and torque values of the contra-angle
handpiece, and not those of the motor, are specified. The control electronics
of the burr drive calculate the motor control based on the specified gear
reduction and the speed and torque settings.
