Motor Nameplate
Motor Overload The overload capability applies to the rated speed range.
Low Overload
After continuous operation at the rated output current, overload may be 110%
rated output current (IL) for 1 minute as long as it is followed by a period of load
less than the rated current so that the output current over the duty cycle does not
exceed the rated output current (IL).
Example: If the duty cycle requires 110% rated output current for 1 minute of
every 10 minutes, the remaining 9 minutes must be at approximately 98% rated
current or less to maintain output current less than 100%. If the requirement is 1
minute out of 60 minutes, the remaining 59 minutes must be at approximately
99% rated current or less.
[Motor NP Volts]
The motor nameplate base voltage defines the output voltage, when operating at rated current, rated speed, and
rated temperature.
[Motor NP FLA]
The motor nameplate 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.
[Motor NP Hz]
The motor nameplate base frequency defines the output frequency, when operating at rated voltage, rated
current, rated speed, and rated temperature.
[Motor NP 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.
[Motor NP Power]
The motor nameplate power is used together with the other nameplate values to calculate default values for
motor parameters to and facilitate the commissioning process. This may be entered in horsepower or in kilowatts
as selected in the previous parameter or kW for certain catalog numbers and HP for others.
[Motor NP Pwr Units]
The rated power of the motor may be entered in horsepower or in kilowatts. This parameter determines the units
on the following parameter.
[Motor Poles]
The number of motor poles - only even numbers are allowed (this may or may not appear on the nameplate).
