Parameters 299
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
.
100%
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.

70%
25…150%
Zero speed load for the motor load curve.
1 = 1%
Defines the motor load curve together with parameters
. Defines the
break point frequency of the load curve i.e. the point at which
the motor load curve begins to decrease from the value of
parameter

45.00 Hz
1.00 … 500.00 Hz
Break point for the motor load curve.
