Code Name/Description Setting range Factory settings
UnS [Rated motor volt.] According to in-
verter performance
In accordance with the in-
verter power and [Stan-
dard Motor Freq.] (bFr)
Rated voltage given on the nameplate.
8I84T2*****.01P-1: 100 to 240 V - 8I84T4*****.01P-1: 200 to 480 V
nCr [Rated mot. current] 0.25 to 1.5 In
1)
In accordance with the in-
verter power and [Stan-
dard Motor Freq.] (bFr)
Rated motor current given on the nameplate.
FrS [Rated motor frequency] 10 to 599 Hz 50 Hz
Rated motor frequency given on the nameplate.
The factory setting is 50 Hz and is replaced by a default of 60 Hz if [Motor frequency] (bFr) is set to 60 Hz.
nSP [Rated motor speed] 0 to 60000 rpm According to in-
verter performance
Rated motor speed given on the nameplate.
0 to 9999 rpm then 10.00 to 60.00 krpm on the integrated display terminal.
If, rather than the rated speed, the nameplate indicates the synchronous speed and the slip in Hz or as a %, calculate the rated speed as follows:
•
Nominal speed = Synchronous speed x 100 - slip in %
100
or
• Nominal speed = Synchronous speed x 50 - slip in Hz
50
(50 Hz motors)
or
• Nominal speed = Synchronous speed x 60 - slip in Hz
60
(60 Hz motors)
tFr [Max frequency] 10 to 599 Hz 60 Hz
The factory setting is 60 Hz and is replaced by a default of 72 Hz if the parameter [Motor frequency] (bFr) is set to 60 Hz.
The maximum value is limited by the following conditions:
• The value of the [Rated motor frequency.] (FrS) should not exceed 10 times.
• It may not exceed 500 Hz for inverter models greater than 37 kW.
tUn [Autotuning] [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.
Caution!
•
All motor parameters ( [Rated voltage Mot.] (UnS) , [Rated motor frequency] (FrS) , [Rated motor current] (nCr) ,
[Rated motor speed] (nSP) , [Rated motor power] (nPr) ) must always be properly configured before the 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 (active at 0).
•
The autotuning has precedence over any operation or premagnetization commands, which are taken into account after
the autotuning sequence.
•
If the autotune fails, the inverter displays [No] (nO) and, depending on the configuration of [Mgt error auto tune] (tnL) ,
can switch into the fault mode [AUTO-TUNE FAULT] (tnF) .
•
Autotuning may last for 1 to 2 seconds. Do not interrupt the process and wait for the display to change to " [Done]
(dOnE) " or to " [No] (nO) ".
Note:
During the autotuning, the rated current flows through the motor.
tUS [Auto tuning status]
(For information only, not adjustable)
[Not done] (tAb)
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) : The autotuning is being executed.
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) : If the parameters are configured manually and not via the autotuning, the parameter [Auto-tune state] (tUS) is equal
to
[Customer spec]
(CUS) .
PHr [Phase rotation] [ABC] (AbC)
AbC [ABC] (AbC) : Clockwise operation.
ACb
[ACB]
(ACb) : Anti-clockwise operation.
This parameter can be used to reverse the motor without changing the cabling.
1) In is the same as the rated current specified in the installation instructions and on the nameplate of the inverter.
