Code Name/Description Factory settings
tFr [Max frequency] 10 to 599 Hz
The factory setting is 60 Hz and is replaced by a default of 72 Hz if the parameter [Standard motor freq. (bFr) is set to 60 Hz.
The maximum value is limited by the following conditions:
•
It is not permitted to exceed 10 times the value of the [rated motor frequency] (FrS)
•
It is not permitted to be exceed 500 Hz if [Motor control type] (Ctt) ( see "Drive parameters (Ctt)" on page 153 ) is not V/F or for inverters
with a nominal value greater than 37 kW.
Values between 500 Hz and 599 Hz are only possible in V/F control and for power limited to 37 kW (50 HP). In this case configure [Motor control
type]] (Ctt) before [Max output frequency] (tFr) .
tUn [Auto-tuning] [No] (nO)
nO [No] (nO) : Autotuning not performed.
YES [Yes] (YES) : The autotuning is being done as soon as possible. The parameter then automatically changes to [Done] (dOnE) .
dOnE [Done] (dOnE) : Use of the values from the previous autotuning.
If one of these parameters is changed after the autotuning [AUTO-TUNE FAULT] (tUn) switches to [No] (nO) and must be performed again.
•
Autotuning is only performed if no stop command has been activated. If a freewheel stop or fast stop function has been assigned to a
logic input, this input must be set to 1 (input active at 0).
• Autotuning has priority over any movement or premagnetization commands. These will be observed only after the autotuning.
• If the autotune fails, the inverter displays [No] (nO) and, depending on the configuration of [Mgt fault auto tune] (tnL) ( see "BRAKE
RESIST PROTECTION (brP-) and AUTO-TUNE FAULT (tnF-)" on page 304 ) switches into the [AUTO-TUNE FAULT] (tnF) fault mode.
• Autotuning may last for 1 to 2 seconds. Do not interrupt the process. Wait until the display switches to " [done] (dOnE) " or " [No] (nO) ".
Note:
During autotuning, the motor is supplied with rated current.
AUt [Automatic autotune] [No] (nO)
nO [No] (nO) : Function not active.
YES [Yes] (YES) : The autotuning is done at every start.
Caution!
See Notes to the [AUTOTUNING FAULT] (tUn) above.
Note:
If [Profile] (CHCF) = [Serie 8] (SE8) , then [autom autotuning] (AUt) is fixed at [No] (nO) .
tUS [Auto tuning status] [Not done] (tAb)
For information only, cannot be modified.
tAb [Not done] (tAb) : The default value of the stator resistance is used to frequency inverter the motor.
PEnd
[Wait]
(PEnd) : Autotuning has been requested but not yet executed.
PrOG [Active] (PrOG) : Autotuning active.
FAIL [Failed] (FAIL) : The autotuning has failed.
dOnE [Done] (dOnE) : The stator resistance measured by the autotuning function is used to control the motor.
CUS [customer-spec] (CUS) : The autotuning has been performed, but then at least one of the parameters defined by this autotuning was changed.
The parameter
[AUTO-TUNE FAULT]
(tUn) then changes again to
[No]
(nO) .
The relevant parameters for the motor measurement are: [R.Stat inp.synMot] (rSAS) , [R.Stat inp. Mot] (rSA) , [Idw] (IdA) , [LFw] (LFA) and
[Cust rotor time const] (trA) .
PHr
[Phase rotation] [ABC]
(AbC)
AbC
ACb
[ABC] (AbC) : Clockwise operation
[ACB] (ACb) : Anti-clockwise operation
This parameter can be used to reverse the motor without changing the cabling.
Note:
Do not change the parameter [phase rotation] (PHr) , if [Motor control type] (Ctt) = [FVC] (FUC) .
see "Drive parameters (Ctt)" on page 153 = [FVC] (FUC) . The direction of rotation must be changed if necessary before or during
the test of the encoder ( see "Encoder testing" on page 157 ) if [Motor control type] (Ctt) is not [FVC] (FUC) .
