Motor Overload Curve
OVLD TIME OUT
(Motor Overload Time Out)
This parameter defines the amount of time
before a motor overload alarm occurs when the
motor is running at the current level defined
below:

This is the other parameter used to define the
overload curve.
FLUX SAT BREAK
(Flux Saturation Break Point)
This parameter sets the flux saturation curve
slope change point.
FLUX SAT SLOPE 1
(Flux Saturation Slope #1)
This parameter sets the flux saturation curve
slope for low fluxes.
FLUX SAT SLOPE 2
(Flux Saturation Slope #2)
This parameter sets the flux saturation curve
slope for high fluxes.
