Parameter ID Units Default Min Max Description
Low Freq Wo 3070 Rad 12.6 0.0 100.0 Pole of hardware RC integrator.
Low freq com gain 3080 1.0 0.5 5.0
Low Frequency compensation gain for
scaling estimated flux.
S/W compensator pole 3090 2.0 0.5 12.6
Pole of software integrator used for flux
estimation.
Parameter ID Units Default Min Max Description
Flux reg prop gain 3110 1.7 0.0 10.0 Flux PI regulator proportional gain term
Flux reg
integral gain
3120 1.0 0.0 1200.0 Flux PI regulator integral gain term
Flux Filter Time Const 3130 sec 0.0667 0.0 10.0
Time constant of the low pass filter used
on the flux error.
Flux demand 3150
per
unit
1.0 0.0 10.0
Sets the flux demand (or desired
Volts-per-Hertz ratio) in per unit.
Flux ramp rate 3160 sec 0.5 0.0 5.0
Sets the ramp time to go from zero to
rated flux. This time establishes the time
to magnetize the motor.
Energy saver min flux 3170 100.0 10.0 125.0
This parameter sets the lowest value of
flux (as a percentage of Rated Motor
Flux) that the drive will apply to an
unloaded motor. Energy Saver is enabled
if a value that is less than the Flux
Demand is entered. The control
establishes the amount of flux (or motor
voltage) that minimizes the losses in the
motor.
Ids DC 3190 % 10.0 1.0 25.0
DC current level used when stator
resistance estimator is enabled.
