Parameter Descriptions
11-11
Set to the power units shown on the motor nameplate. This
parameter determines the units for parameter 45.
Motor Overload Hz is used to allow you to adjust the response of
the motor thermal overload to lower motor speeds (lower output
frequencies) where a higher degree of protection may be required
due to decreased motor cooling.
This parameter selects the output frequency below which the motor
operating current is derated. The motor thermal overload could
generate a fault at below rated current. For all settings of overload
Hz other than zero, the overload capacity is reduced to 70% when
output frequency is zero.
