Description
Defines the motor load curve together with parameters
Zero speed load and 35.53 Break point.
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

maximum motor load at zero speed of the load curve. A
higher value can be used if the motor has an external motor
fan to boost the cooling. See the motor manufacturer's
recommendations.
