Motor Nameplate
Data
These parameters provide motor information to the drive, so the drive can both
protect the motor and also make internal adjustments to provide the best
performance.
[Motor NP Volts]
The rated voltage as stated on the motor nameplate.
[Motor NP FLA]
The rated full load amps as stated on the motor nameplate.
[Motor NP Hz]
The rated base frequency as stated on the motor nameplate.
[Motor NP RPM]
The rated base speed in RPM as stated on the motor nameplate.
[Motor NP Power]
The rated power as stated on the motor nameplate. This may be entered in
horsepower or in kilowatts as selected in [Mtr NP Pwr Units], parameter 46.
[Mtr NP Pwr Units]
Determines the units for [Motor NP Power]. Possible settings are:
• 0 “Horsepower” - units are displayed in HP.
• 1 “kilowatts” - units are displayed in kW.
• 2 “Convert HP” - converts units to HP (from kW) by dividing [Motor NP
Power] by 0.746 (PowerFlex 700VC Only).
• 3 “Covert kW” - converts units to kW (from HP) by multiplying [Motor NP
Power] by 0.746 (PowerFlex 700VC Only).
[Motor Poles]
Defines the number of poles in the motor. [Motor Poles] is calculated automatically
if the user enters the motor nameplate data through the Assisted Start-up menu of
an LCD HIM. The number of motor poles is defined by:
