P-27 Voltage filter time const.
Range:
Function:
0.001 s
*
[0.001 - 1
s]
Supply voltage filter time constant is used
for reducing the influence of high
frequency ripples and system resonances
in the calculation of machine supply
voltage. Without this filter, the ripples in
the currents can distort the calculated
voltage and affect the stability of the
system.

P-30 Stator Resistance (Rs)
Range:
Function:
1.4000
Ohm
*
[0.0140 -
140.0000
Ohm]
NOTICE
This parameter cannot be
adjusted while the motor is
running.
For PM motors, see the description
under
parameter P-37 d-axis Inductance
Set the stator resistance value. Enter the
value from a motor datasheet or
perform an Auto Tune on a cold motor.
P-31 Rotor Resistance (Rr)
Range:
Function:
1.0000
Ohm
*
[0.0100 -
100.0000
Ohm]
Fine-tuning R
r
will improve shaft
performance. Set the rotor resistance value
using one of these methods:
1.
Run an Auto Tune on a cold
motor. The frequency converter
will measure the value from the
motor. All compensations are
reset to 100%.
2.
Enter the R
r
value manually.
Obtain the value from the motor
supplier.
3.
Use the R
r
default setting. The
frequency converter establishes
the setting on the basis of the
motor nameplate data.
P-35 Main Reactance (Xh)
Range:

NOTICE
Parameter P-35 Main Reactance

does not have effect when
parameter P-20 Motor
Construction
=[1] PM, non salient
SPM.
Set the main reactance of the motor
using 1 of these methods:
•
Run an Auto Tune on a cold
motor. The frequency
converter measures the value
from the motor.
•
Enter the X
h
value manually.
Obtain the value from the
motor supplier.
•
Use the X
h
default setting. The
frequency converter
establishes the setting on the
basis of the motor nameplate
data.
P-36 Iron Loss Resistance (Rfe)
Range:
Function:
10000.000
Ohm
*
[0 -
10000.000
Ohm]
NOTICE
This parameter cannot be
adjusted while the motor is
running.
Enter the equivalent ironloss
resistance (R
Fe
) value to compensate
for iron losses in the motor.
The R
Fe
value cannot be found by
performing an Auto Tune.
The R
Fe
value is especially important
in torque control applications. If R
Fe
is
unknown, leave
on default
setting.
P-37 d-axis Inductance (Ld)
Range:
Function:
0.000
mH
*
[0.000 -
1000.000 mH]
NOTICE
This parameter is only active
when
is set to
[1] PM, non-
salient SPM
.
Enter the value of the d-axis
inductance. Obtain the value from the
PM motor datasheet.
