DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
When [Motor fluxing] (FLU) is set to [Continuous] (FCt), the drive automatically builds up flux.
Check this action will not endanger personnel or equipment in any way.
Failure to follow these instructions will result in death or serious injury.
CAUTION
RISK OF DAMAGE TO THE MOTOR
Check that the motor will withstand this current without overheating.
Failure to follow these instructions can result in equipment damage.
FnC
FCt
FnO
[Not cont.] (FnC): Non-continuous mode
[Continuous] (FCt): Continuous mode.
This option is not possible if [Auto DC injection] (AdC) page 161
is [Yes] (YES) or if [Type of stop] (Stt) page 158 is
[Freewheel] (nSt).
[No] (FnO): Function inactive
In order to obtain rapid high torque on startup, magnetic flux needs to already have been established in the motor.
In [Continuous] (FCt) mode, the drive automatically builds up flux when it is powered up.
In [Not cont.] (FnC) mode, fluxing occurs when the motor starts up.
The flux current is greater than [Rated mot. current] (nCr) (configured rated motor current) when the flux is established and
is then adjusted to the motor magnetizing current.
If [Motor control type] (Ctt) page 92
is set to [Sync. mot.] (SYn), the [Motor fluxing] (FLU) parameter causes the
alignment of the rotor and not the fluxing.
If [Brake assignment] (bLC) page 179
is not [No] (nO), the [Motor fluxing] (FLU) parameter has no effect.
FLI [Fluxing assignment]
[No] (nO)

CAUTION
RISK OF DAMAGE TO THE MOTOR
Check that the motor will withstand this current without overheating.
Failure to follow these instructions can result in equipment damage.
nO
LI1
...
Assignment is only possible if [Motor fluxing] (FLU) is set to [Not cont.] (FnC).
If an LI or a bit is assigned to the motor fluxing command, flux is built up when the assigned input or bit is at 1.
If an LI or a bit has not been assigned, or if the assigned LI or bit is at 0 when a run command is sent, fluxing occurs when the
motor starts.
[No] (nO): Not assigned
[LI1] (LI1): Logical input LI1
[...] (...): See the assignment conditions on page 138
