250 Parameters
35.51 Motor load curve Defines the motor load curve together with parameters
35.52 Zero speed load and 35.53 Break point . 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
99.06 Motor nominal
current (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
temperature .
110%
50…150% Maximum load for the motor load curve. 1 = 1%
35.52 Zero speed load Defines the motor load curve together with parameters
35.51 Motor load curve and 35.53 Break point . 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
35.51 Motor load curve .
70%
25…150% Zero speed load for the motor load curve. 1 = 1%
35.53 Break point Defines the motor load curve together with parameters
35.51 Motor load curve and 35.52 Zero speed load .
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
35.51 Motor load curve
towards the value of parameter 35.52 Zero speed load .
See parameter 35.51 Motor load curve .
45.00 Hz
1.00…500.00 Hz Break point for the motor load curve. See par.
