C-78 Parameter ReferenceAC30 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 flexible Volts-to-frequency templates. Starting torque performance can also be tailored through the Fixed Boost, Acceleration Boost and Auto Boostparameters.Parameter Name No. Path Default Range Units WritableVHz Shape 0422 Setup::Motor Control ::Control and TypeParameters::Motor Control::Fluxing VHz0 0:LINEAR LAW1:FAN LAW2:USER DEFINED3:APPLICATION DEFINEDSTOPPEDType 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 matches the load requirement for fanand most pump applications2 : USER DEFINED This gives a user defined flux characteristic up to the Base Frequency.3 : APPLICATION DEFINED This gives a user the ability to set up and apply fluxing law from the application layer.V/F SHAPELINEARFREQUENCY= BASE FREQUENCY100%CONSTANTPOWER RANGE(field weakening)OUTPUT VOLTSf Bf BQUADRATIC LAWCONSTANTTORQUERANGEFixed Boost 0447 Same as PNO 422 0.0 0.0 to 25.0 % ALWAYS
