0The drive control unit is powered from the drive power
unit it is connected to.
Note: If reduced run (see section Reduced run
function (page 143)) is required, select External 24V or
Redundant external 24V instead.
Internal 24V
1The 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.
External 24V
2
(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 (AFEC External power signal
missing). 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.
