Enables adaptive voltage limits.
Adaptive voltage limits can be used if, for example, an IGBT
supply unit is used to raise the DC voltage level. If the
communication between the inverter and the IGBT supply
unit is active (95.20 HW options word
are related to the DC voltage reference transmitted to the
supply unit (94.20 DC voltage reference) assuming that the
reference is high enough. Otherwise, the limits are
calculated based on the measured DC voltage at the end of
the pre-charging sequence.
This function is also useful if the AC supply voltage to the
drive is high, as the warning levels are raised accordingly.
Adaptive voltage limits disabled.
Adaptive voltage limits enabled.
Specifies how the control unit of the drive is powered.
The drive control unit is powered from the drive power unit it
is connected to.
The drive control unit is powered from an external power
supply.
(Type BCU control units only) The drive control unit is
powered from two redundant external power supplies. The
loss of one of the supplies generates a warning
External power signal missing).
