Explanatory notes
• When the time MPTx elapses the inverter module switches to the
“Open-loop control/Closed-loop control active” state. That means
that during the magnetization phase voltage frequency control is
deactivated for a short time.
• The transition can be made directly from the magnetization phase to
current injection.
• The magnetization time for control modes SFC and FOR is calcu-
lated during auto-tuning (163-ENSC) and should only be altered by
highly experienced control engineers.
