: Output frequency
Adjustment range : ± 400.0 Hz
5.01
is the drive output frequency.
: Output voltage
Adjustment range : 0 to
5.09
Volts
This is the rms voltage at the drive output.
: Output power
Adjustment range : 0 to 200 kW
5.03
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 (I max = 150% of drive rated current).
: Motor speed
Adjustment range : ± 2 x
1.06
rpm
The motor speed is calculated according to the formula:
5.04
(rpm) =
: DC bus voltage
Adjustment range : Voltage code 200 = 0 to 420 V
Voltage code 400 = 0 to 860 V
Indicates the DC bus voltage measurement.
: Motor rated frequency
Adjustment range : 0 to 400.0 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 drive rated current (A)
Factory setting
: Motor rated current corresponding
to the drive rating (see section 7.4)
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 : 0 to 9999 rpm
Factory setting
: Motor rated speed corresponding
to the drive rating (see section 7.4)
This is the on-load speed of the motor indicated on the
nameplate.
:Motor rated voltage
Adjustment range : 0 to 480V
Factory setting
: Eur (voltage code 200) : 200 V,
USA (voltage code 200) : 230 V
Eur (voltage code 400) : 400 V,
USA (voltage code 400) : 460 V
Defines the voltage/frequency ratio as follows:
* If the fixed boost has been selected
5.14
= 2.
: Rated power factor (Cos
ϕ
)
Adjustment range : 0 to 1.00
Factory setting
: 0.85
The power factor is measured automatically during a level 2
autotune phase (see
5.12
) and set in this parameter. If it has
not been possible to carry out the autotune procedure, enter
the Cos
ϕ
value indicated on the motor nameplate.
:Number of motor poles
Adjustment range : 0 to 4
Factory setting
: 0
0 (Automatic) (Auto)
1 (2 Poles) (2P)
2 (4 Poles) (4P)
3 (6 Poles) (6P)
4 (8 Poles) (8P)
When this parameter is at 0, the drive automatically
calculates the number of poles according to the rated speed
(
5.08
) and the rated frequency (
5.06
). However, the value
can be entered directly in accordance with the table below:
