152 ACOPOSinverter P84 User's Manual 2.10
The parameters in the [DRIVE DATA] (drC-) menu can only be changed if the inverter is stopped and no run
command is present, with the following limitations:
• [AUTOTUNE ERROR] (tUn) ( see "Drive parameters (tFr - PHr)" on page 152 ) can cause a motor start.
•
A parameter whose code contains the arrow sign, can be modified with the frequency inverter running or
stopped.
Drive parameters
Code Name/Description Setting range Factory settings
bFr [Standard mot. freq] [50 Hz IEC] (50)
50
60
[50 Hz IEC] (50) : IEC
[60 Hz NEMA] (60) : NEMA
This parameter is used to change the default settings of the following parameters: [high speed] (HSP) , [F. thresh. Mot]] (Ftd) ,
[Mot. rated volt] (UnS) , [Motor rated frequency] (FrS) , [Max. output freq.] (tFr) , [Motor rated current] (nCr) , [Motor rated speed] (nSP)
and [brake tightening power] (Ibr) .
nPr [Rated motor power] According to in-
verter performance
According to in-
verter performance
This parameter cannot be accessed if [Motor control type] (Ctt) ( see "Drive parameters (Ctt)" on page 153 ) = [Sync. Motor.] (SYn) .
Rated motor power in accordance with the nameplate in kW if [Standard Motorfreq.] (bFr) = [50 Hz IEC] (50) ; in PS (HP), if
[Standard Motorfreq.] (bFr) = [60 Hz NEMA] (60) .
UnS [Rated motor volt.] According to in-
verter performance
In accordance with
the inverter power and
[Standard Motor Freq.] (bFr)
This parameter cannot be accessed if [Motor control type] (Ctt) ( see "Drive parameters (Ctt)" on page 153 ) = [Sync. Motor.] (SYn) .
Rated motor voltage given on the nameplate.
8I84T2******.01P-1: 100 to 240 V - 8I84T4*****0.01P-1: 200 to 480 V
nCr [Rated mot. current] 0.25 to 1.5 In
1)
In accordance with
the inverter power and
[Standard Motor Freq.] (bFr)
This parameter cannot be accessed if [Motor control type] (Ctt) ( see "Drive parameters (Ctt)" on page 153 ) = [Sync. Motor.] (SYn) .
Rated motor current given on the nameplate.
FrS [Rated motor frequency] 10 to 599 Hz 50 Hz
This parameter cannot be accessed if [Motor control type] (Ctt) ( see "Drive parameters (Ctt)" on page 153 ) = [Sync. Motor.] (SYn) .
Rated motor frequency given on the nameplate.
The factory setting is 50 Hz and is replaced by a default of 60 Hz if [Standard motor freq. (bFr) is set to 60 Hz. The maximum value is limited to 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 [Rated motor frequency] (FrS) .
InSP [Increments rpm] [x1 tr/mn] (1)
Increment of the parameter [rated motor speed] (nSP) .
1 [x1 tr/mn] (1): Increment of 1 U/min; is used if the [rated motor speed] (nSP) does not exceed 65535 r/min.
10 [x10 tr/mn] (10): Increment of 10 U/min; is used if the [rated motor speed] (nSP) exceeds 65535 r/min.
Note:
Each change of [increments rpm] (InSP) sets the parameter [rated motor speed] (nSP) back to the factory setting.
nSP [Rated motor speed] 0 to 96000 rpm According to in-
verter performance
The parameter is not accessible if [motor control type] (Ctt) = [Sync. Motor] (SYn) .
Rated motor speed given on the nameplate
Adjustable from 0 to 65535 rpm, if [Increments rpm] (InSP) = [x1 tr/mn] (1) or from 0.00 to 96.00 kr/min, if [Increments rpm] (InSP) = [x10 tr/
mn] (10) . 0 to 9999 rpm then 10.00 to 65.53 or 96.00 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)
1) In is the same as the rated current specified in the installation instructions and on the nameplate of the inverter.
