MOT LOAD CURVE
(see above)
Defines the load curve together with parameters
and
.
The value is given in percent of nominal motor current. When the parameter is set to 100%, the
maximum load is equal to the value of the 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
.
50…150%
Motor current above breakpoint.
45.07
ZERO SPEED LOAD
(see above)
Defines the load curve together with parameters
and
. 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.
The value is given in percent of nominal motor current.
The load curve is used by the motor thermal protection model when parameter
.
50…150%
Motor current at zero speed.
45.08
BREAK POINT
(see above)
Defines the load curve together with parameters
. Defines the break point frequency of the load curve, ie, the point at which the motor load curve
begins to decrease from the value of parameter
to the value of parameter
.
The load curve is used by the motor thermal protection model when parameter
.
0.01…500 Hz
Load curve breakpoint.
