288 Parameters
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 (
), the voltage limits are
related to the DC voltage reference transmitted to the supply
unit 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.
b15)
Disable
Adaptive voltage limits disabled.
0
Enable
Adaptive voltage limits enabled.
1
Specifies how the control unit of the drive is powered.
The default value depends on the type of the control unit and
the setting of parameter
(ZCU);
(BCU;
b4)
Internal 24V
The drive control unit is powered from the drive power unit it is
connected to.
Note:
If reduced run (see page
or
instead.
0
External 24V
The drive control unit is powered from an external power
supply. The drive power unit and power unit link faults are
masked when the drive is in stopped state, so the main circuit
can be powered down without faults while the control unit is
powered.
1
Redundant external
24V
(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 (
). The drive power unit and
power unit link faults are masked when the drive is in stopped
state, so the main circuit can be powered down without faults
while the control unit is powered.
