Description
Defines the load curve together with parameters
ZERO SPEED LOAD
With the default value 100%, motor overload protection is
functioning when the constant current exceeds 127% of the
parameter 9906 MOTOR NOM CURR
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 nominal motor current, set parameter
91% (= 115/127·100%).
