Parameter Descriptions
12-11
Sets the output frequency below which the motor operating current
is derated. This allows the motor thermal overload to generate a
fault below rated current. Note that for all settings of overload Hz
other than 0.0, the overload capacity is reduced to 70% when output
frequency is zero.
Sets the continuous current operating level for the motor.
The parameter can be used to raise the level of current that will
cause the motor thermal overload to trip. The effective overload
factor is a combination of parameters 47 and 48.
Motor FLA x OL Factor = Operating Level (Continuous)
