214 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.

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 .
