200 Parameters
31.10
Mot load curve
Defines the load curve together with parameters
When the parameter is set to 100%, the maximum load is
equal to 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.
The load curve is used by the motor thermal protection
model when parameter
is set to
50 … 150%
Maximum load for the motor load curve.
1 = 1%
31.11
Zero speed load
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.
See parameter
.
50 … 150%
Zero speed load for the motor load curve.
1 = 1%
31.12
Break point
Defines the motor load curve together with parameters
and
. 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
towards the value of
parameter
See parameter
.
0.01 … 500.00 Hz
Break point for the motor load curve.
100 = 1 Hz
No.
