FLUXING
SETUP::MOTOR CONTROL::FLUXING
Designed for VOLTS/Hz motor Control Mode.
This function block allows user parameterisation of the conventional (volts/hertz) fluxing strategy of the Drive. This is
achieved though three flexible Volts-to-frequency templates. Starting torque performance can also be tailored through the
FIXED BOOST, ACCELRTN BOOST and AUTO BOOST parameters.
Parameter Descriptions
V/F SHAPE
PREF: 21.01
Default: 0
Range: See below
This parameter determines the type of volts to frequency template that is used to flux the motor. The choices for this parameter
are:
Enumerated Value
:
V/F Shape
0 : LINEAR LAW
This gives a constant flux characteristic up to the BASE FREQUENCY (see MOTOR
INDUCTION function block).
1 : FAN LAW
This gives a quadratic flux characteristic up to the BASE FREQUENCY. This matches
the load requirement for fan and most pump applications
2 : USER DEFINED
This gives a user defined flux characteristic up to the BASE FREQUENCY.
