5.6.2 - Explanation of parameters in menu 5
: Output fre q uency
Adjustment range : ± 590.0 Hz
Indicates the drive output frequency.
: Output volta g e
Adjustment range : 0 to 999 V
Fondamental voltage value at the drive output.
: Output power
Adjustment range :
05.03
is the calculated motor active power.
If this parameter has been assigned to an analog output via
menu 7, 10 V corresponds to the maximum power
measurable by the drive (max. drive current = 2.22 x
11.32
).
: Motor speed
Adjustment range : ± 2 x
01.06
rpm
The motor speed is calculated from the output frequency
05.01
according to the formula:
: DC bus volta g e
Adjustment range : 0 to 1300 V
Indicates the DC bus voltage measurement.
: Motor rated fre q uency
Adjustment range : 0.0 to 590.0 Hz
Factory setting
: Eur = 50.0 Hz
USA = 60.0 Hz
This is the point at which motor operation changes from
constant torque to constant power.
In standard operation, it is the frequency indicated on the
motor nameplate.
: Motor rated current
Adjustment range : 0 to I
co
(A)
Factory setting : Motor rated current corresponding
to the drive rating (see section 5.6.3)
This is the value of the motor rated current indicated on the
nameplate. The overload is calculated from this value.
: Motor rated speed
Adjustment range : 1 to 32000 rpm
Factory setting
: Motor rated speed corresponding
to the drive rating (see section 5.6.3)
This is the on-load speed of the motor shown on the
nameplate.
Note: This value must take into account the slip of the
asynchronous motor with respect to the synchronous speed.
Under no circumstances must this slip be negative.
: Motor rated volta g e
Adjustment range : 0 to 999 V
Factory setting
: Eur: 400 V , USA: 460 V
Enter the rated voltage shown on the nameplate taking
account of the normal power supply conditions.
Defines the voltage/frequency ratio as follows:
* If fixed boost has been selected
05.14
= LINEAR V/F (2),
the boost value is set via
05.15
.
: Rated power factor
Adjustment range : 0 to 1.00
Factory setting
: 0.85
The power factor is measured automatically during a level 2
autotune phase (see
05.12
) and set in this parameter. If it
has not been possible to carry out the autotune procedure,
enter the Cos
M
value indicated on the motor nameplate.
: Number of motor poles
Adjustment range : Automatic (0), 2 Poles (1), 4 Poles (2),
6 Poles (3), 8 Poles (4), 10 Poles (5),
12 Poles (6), 14 Poles (7), 16 Poles (8)
Factory setting : Automatic (0)
When this parameter is at 0 (Automatic), the drive automatically
calculates the number of poles according to the rated speed
(
05.08
) and the rated frequency (
05.06
). However, the value
can be entered directly in accordance with the table below:
