Parameter Descriptions
12-9
Set to the motor nameplate rated volts. The motor nameplate base
voltage defines the output voltage when operating at rated current,
rated speed, and rated temperature.
Set to the motor nameplate rated full load amps. The motor
nameplate FLA defines the output amps when operating at rated
voltage, rated speed, and rated temperature. It is used in the motor
thermal overload and in the calculation of slip.
This parameter, set in the start-up procedure, is adjustable from
0 - 200% of drive rating and should be set for the actual motor FLA
rating.
About the Motor Thermal Overload Function
The operation of the overload is actually based on three
parameters: Motor NP FLA (42), Motor OL Factor (48), and 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
function.
Since the motor thermal overload function cannot distinguish
individual currents in a multi-motor 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.
Motor Overload Hz (47) 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.
