1.10 FLUX CURRENT CONFIGURATIONS (FLUX CONFIG)
1.10.1 Control of the Flux Current Maximum Limit (Flux Max Limit)
This Function allows the user to control the maximum value of the Flux current. The function is linked to the
control of the voltage loop. In a condition where the Flux is = 0, the voltage regulator prevails by controlling the
motor. It means that it is only possible to further limit the requirement of the voltage loop.
In case the Drive is active in the constant torque area, it is possible to set an overflux up to 115% of the rated flux.
This is possible, obviously, only if the motor/drive combination is in a position to supply a sufficient magnetizing
current.
The Flux max lim src source allows to select the function control signal. In the standard configuration the
source is connected to Int flx maxlim, a parameter which can be set in cfg.
NOTE! The Function is active only in a Sensorless and Field oriented mode.
The input is: · Flux max lim src

1.10.2 Control of the Magnetizing Current (Magnetiz Config)
The Function is active only in a Sensorless and Field oriented mode and is useful for undesidered motor shaft
rotation. It allows to lock the Flux position, Lock flux, and to set a Ramp time of the magnetizing current Magn
ramp time.
In the
configurations it is possible to start the Lock flux function. Via the Lock flux pos parameter, it is possible
to lock the flux position when the following selected condition is satisfied:
· Off non-active function
· At magnetization to the magnetizing current
· At Spd=0 with a Speed 0
· At magn & Spd=0 to the magnetizing current and with a Speed 0
· At magn and Ref=0 magnetizing current and Ref 0
