047 [Motor OL Hertz]
Selects the output frequency below which
the motor operating current is derated.
The motor thermal overload will generate
a fault at lower levels of current. For all
settings of overload Hz other than zero,
the overload capacity is reduced to 70%
when output frequency is zero.

048 [Motor OL Factor]
Sets the operating level for the motor
overload.
This 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 047 and 048.
