[FLUXING BY LI] (FLI-)
Code Name/Description Factory settings
FLI- [FLUXING BY LI]
FLU [Motor fluxing]
1)
[No] (FnO)
FnC [not perm.] (FnC) : Non-permanent mode.
FCt
[permanent]
(FCt) : Permanent mode. This option is not possible if
[Auto DC injection]
(AdC) ( see "[Auto DC injection] AdC-" on page 208 ) is
set to [Yes] (YES) or if [STOP MODE] (Stt) ( see "STOP MODE (Stt-)" on page 206 ) has been set to [freewheel stop] (nSt) .
FnO [No] (FnO) : Function not active. This option is not possible if [Motor control type] (Ctt) ( see "Drive parameters (Ctt)" on page 153 ) is set to
[SVC I] (CUC) or [FVC] (FUC) .
If [Motor control type] (Ctt) ( see "Drive parameters (Ctt)" on page 153 ) is set to [SVC I] (CUC) [FVC] (FUC) or [Sync. Motor] (SYn) the factory
setting is replaced by [not perm.] (FnC) .
In order to obtain rapid high torque on startup, magnetic flux needs to already have been established in the motor.
• In the mode [permanent] (FCt) the inverter automatically creates the magnetic flux at its start.
• In the mode [not perm.] (FnC) the magnetization occurs when the motor has started.
The magnetic flux current is greater than the [rated motor current] (nCr) (configured rated current of the motor), if the magnetization has been
established. After this, the flux current will be adjusted to the motor's magnetizing current.
Caution!
Check that the motor will withstand this current without overheating.
Failure to follow this instruction can result in equipment damage.
If
[motor control type]
(Ctt) ( see "Drive parameters (Ctt)" on page 153 ) =
[Sync. Motor]
(SYn) is set, the parameter
[Magnet Mot]
(FLU) results
in the assignment of the rotor and not of the magnetization.
If [BRAKE LOGIC] (bLC) ( see "[BRAKE LOGIC CONTROL] (bLC-)" on page 223 ) is not [No] (nO) , the parameter [Magnet Mot] (FLU) has
no effect.
FLI [Fluxing assignment] [No] (nO)
nO [No] (nO) : Function not active.

[...] (...) : See the assignment conditions
The assignment is only possible if [Magnet Mot] (FLU) = [not perm.] (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.
1) This parameter can also be accessed via the [SETTINGS] (SEt-) menu.
Parameter that can be modified during operation or when stopped.
