Defines the ambient temperature of the motor for the motor
thermal protection model. The unit is selected by parameter
96.16 Unit selection.
The motor thermal protection model estimates the motor
temperature on the basis of parameters 35.50...35.55. The
motor temperature increases if it operates in the region above
the load curve, and decreases if it operates in the region
below the load curve.
WARNING! The model cannot protect the motor if the
motor does not cool properly because of dust, dirt, etc.

used by the motor thermal protection model to estimate the
motor temperature.
When the parameter is set to 100%, the maximum load is
taken as the value of parameter
(higher loads heat up the motor). The load curve level should
be adjusted if the ambient temperature differs from the
nominal value set in 35.50 Motor ambient
