Description
System
parameters
Operating modes
There are 12 operating modes available,
Mode 3 (internal)
See section 4.1.3 for details
Start mode
Is used for setting the power on mode of the AHF.
“Auto” mode: The AHF automatically compensates the load
harmonics current.
“Manual” mode starts the compensation only once the
power on command has been received (Power ON).

current
3rd to 13th harmonic
angle
2)
Correction of the phase angle for the respective harmonic
