4. Parameters 1 [Motor NP Volts] and 3 [Motor NP Hertz] set the upper
portion of the curve to match the motor design and mark the beginning of
the constant horsepower region.
5. Parameters 531 [Maximum Voltage] and 532 [Maximum Freq] slope that
portion of the curve used above base speed.

[Motor NP Volts] 1 The motor nameplate base voltage defines the output voltage, when
operating at rated current, rated speed, and rated temperature.
[Motor NP FLA] 2 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 Hertz] 3 The motor nameplate base frequency defines the output frequency,
when operating at rated voltage, rated current, rated speed, and rated
temperature.
[Motor NP RPM] 4 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] 5 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] 6 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] 7 The number of motor poles - only even numbers are allowed (this may or
may not appear on the nameplate)
