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
SMOt [Saliency mot. state]
g
(for information only, cannot be modified)
Information on synchronous motor saliency.
This parameter can be accessed if [Tune selection] (StUN) is set to [Measure] (MEAS).
Note: In case of motor with low saliency, the standard control law is advised.
nO
LLS
MLS
HLS
[No] (nO): Tune not done
[Low salient] (LLS): Low saliency level (Recommended configuration: [Angle setting type] (ASt) = [PSI align] (PSI) or
[PSIO align] (PSIO) and [HF inj. activation] (HFI) = [No] (nO)).
[Med salient] (MLS): Medium saliency level ([Angle setting type] (ASt) = [SPM align] (SPMA) is possible.
[HF inj. activation] (HFI) = [Yes] (YES) could work).
[High salient] (HLS): High saliency level ([Angle setting type] (ASt) = [IPM align] (IPMA) is possible.
[HF inj. activation] (HFI) = [Yes] (YES) is possible).
ASt [Angle setting type]
[PSIO align.] (PSIO)
g
Mode for measuring the phase-shift angle. Visible only if [Motor control type] (Ctt) is set to [Sync. mot.] (SYn).
[PSI align] (PSI) and [PSIO align] (PSIO) are working for all type of synchronous motors. [SPM align] (SPMA) and
[IPM align] (IPMA) increase performances depending on the type of synchronous motor.
IPMA
SPMA
PSI
PSIO
nO
[IPM align] (IPMA): Alignment for IPM motor. Alignment mode for Interior-buried Permanent Magnet motor (usually, this kind
of motor has a high saliency level). It uses high frequency injection, which is less noisy than standard alignment mode.
[SPM align] (SPMA): Alignment for SPM motor. Mode for Surface-mounted Permanent Magnet motor (usually, this kind of
motor has a medium or low saliency level). It uses high frequency injection, which is less noisy than standard alignment mode.
[PSI align] (PSI): Pulse signal injection. Standard alignment mode by pulse signal injection.
[PSIO align] (PSIO): Pulse signal injection - Optimized. Standard optimized alignment mode by pulse signal injection. The
phase shift angle measurement time is reduced after the first run order or tune operation, even if the drive has been turned off.
[No align] (nO): No alignment
