204 Parameters
Defines the motor load curve together with parameters
and
The load curve is
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
110%
50…150%
Maximum load for the motor load curve.
1 = 1%
Defines the motor load curve together with parameters
. Defines the
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.

100%
50…150%
Zero speed load for the motor load curve.
1 = 1%
Defines the motor load curve together with parameters

break point frequency of the load curve ie. the point at which
the motor load curve begins to decrease from the value of
parameter
towards the value of
