OTOR THERMAL TIME CONSTANT
This time can be set between 1 and 200 minutes.
This is the thermal time constant of the motor. The bigger the motor, the bigger
the time constant. The time constant is the time within which the calculated
thermal model has reached 63% of its final value.
The motor thermal time is specific to the motor design and it varies between
different motor manufacturers.
