SP600 AC Drive User Manual
Since the motor thermal overload cannot distinguish individual
currents in a multimotor application, it is suggested that it be
disabled in these cases. This can be done by setting the correct bit
in Fault Config (238) to zero to disable the motor thermal overload.
The operation of the overload is actually based on three
parameters: 1) Motor NP FLA (42), 2) Motor OL Factor (48), and 3)
Motor OL Hertz (47). The motor nameplate full load amps is then
multiplied by the motor overload factor to allow you to re-define the
continuous level of current allowed by the motor thermal overload.
Set to the motor nameplate rated frequency. The motor nameplate
base frequency defines the output frequency when operating at
rated voltage, rated current, rated speed, and rated temperature.
Set to the motor nameplate rated RPM. The motor nameplate RPM
defines the rated speed when operating at motor nameplate base
frequency, rated current, base voltage, and rated temperature. This
is used to calculate slip.
Set to the motor nameplate rated power. The motor nameplate
power is used with the other nameplate values to calculate default
values for motor parameters to assist the commissioning process.
This may be entered in horsepower or in kilowatts as selected in
parameter 46.
