Description
Def
3007
MOT LOAD CURVE
Defines the load curve together with parameters
3008
ZERO SPEED LOAD
and
3009
BREAK POINT FREQ. With the default value 100%, motor
overload protection is functioning when the constant current exceeds 127%
of the parameter
9906
MOTOR NOM CURR value.
The default overloadability is at the same level as what motor manufacturers
typically allow below 30 °C (86 °F) ambient temperature and below 1000 m
(3300 ft) altitude. When the ambient temperature exceeds 30 °C (86 °F) or
the installation altitude is over 1000 m (3300 ft), decrease the parameter
3007 value according to the motor manufacturer
’s recommendation.
Example
: If the constant protection level needs to be 115% of the motor
nominal current, set parameter 3007 value to 91% (= 115/127·100%).
