Parameters described in this page can be accessed by:
tUnU [Auto tuning usage]
[Therm Mot] (tM)
nO
tM
Ct
This parameter shows the way used to modify the motor parameters according to its estimated thermal state.
[No] (nO): No thermal state estimation
[Therm Mot] (tM): Statoric thermal state estimation based on nominal current and current consumed by the motor
[Cold tun] (Ct): Statoric thermal state estimation based on statoric resistance measured at the first cold tune and tune done
at each power up
AUt [Automatic autotune]
[No] (nO)
T
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
When [Automatic autotune] (AUt) is changed from [No] (nO), Autotune will be performed every time the
power will be switched on.
Check this action will not endanger personnel or equipment in any way.
Failure to follow these instructions will result in death or serious injury.
The motor must be stopped when switching on the drive.
[Automatic autotune] (AUt) is forced to [Yes] (YES) if [Auto tuning usage] (tUnU) is set to [Cold tun] (Ct). The value
of motor statoric resistance measured during the tune is used to estimate the thermal state of the motor at power up.
nO
YES
[No] (nO): Function deactivated
[Yes] (YES): A tune is automatically done at each power up
FLU [Motor fluxing]
[No] (FnO)

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.

If [Motor control type] (Ctt) page 92
is set to [Sync. mot.] (SYn), the factory setting is replaced by [Not cont.] (FnC).
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.
[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. This option is not possible if [Brake assignment] (bLC) page 179
is not [No] (nO).
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.
