D-37 Parameter ReferenceAC30V series Variable Speed DriveFluxing VHzParameters::Motor Control::Fluxing VHzDesigned for VOLTS/Hz motor Control Mode.This function allows user parameterisation of the conventional (volts/hertz) fluxing strategy of the Drive. This is achieved through three flexibleVolts-to-frequency templates. Starting torque performance can also be tailored through the Fixed Boost, Acceleration Boost and Auto Boostparameters.PNO Parameter Descriptions0422 VHz ShapeType of volts to frequency template to flux the motor. The choices for this parameter are:Enumerated Value : VHz Shape0 : LINEAR LAW This gives a constant flux characteristic up to the Base Frequency (see Motor Nameplate function).1 : FAN LAW This gives a quadratic flux characteristic up to the Base Frequency. This matchesthe load requirement for fan and most pump applications2 : USER DEFINED This gives a user defined flux characteristic up to the Base Frequency.V/F SHAPELINEARFREQUENCY= BASE FREQUENCY100%CONSTANTPOWER RANGE(field weakening)OUTPUT VOLTSf Bf BQUADRATIC LAWCONSTANTTORQUERANGE
