P-33 Stator Leakage Reactance (X1)
Range:
Function:
3.
Use the X
1
default setting. The
frequency converter establishes
the setting on the basis of the
motor name plate data.
NOTE
P-33 Stator Leakage Reactance (X1) will not have effect
when P-20 Motor Construction = [1] PM, non salient SPM.
P-34 Rotor Leakage Reactance (X2)
Range:
Function:
4.0000
Ohm
*
[0.0400 -
400.0000
Ohm]
Set the rotor leakage reactance of the
motor using one of these methods:
1.
Run an Auto Tune on a cold
motor. The frequency converter
will measure the value from the
motor.
2.
Enter the X
2
value manually.
Obtain the value from the motor
supplier.
3.
Use the X
2
default setting. The
frequency converter establishes
the setting on the basis of the
motor name plate data.
NOTE
P-34 Rotor Leakage Reactance (X2) will not have effect when
P-20 Motor Construction = [1] PM, non salient SPM.
P-35 Main Reactance (Xh)
Range:
Function:
100.0000
Ohm
*
[1.0000 -
10000.0000
Ohm]
Set the main reactance of the motor
using one of these methods:
1.
Run an Auto Tune on a cold
motor. The frequency
converter will measure the
value from the motor.
2.
Enter the X
h
value manually.
Obtain the value from the
motor supplier.
3.
Use the X
h
default setting.
The frequency converter
establishes the setting on
the basis of the motor name
plate data.
P-36 Iron Loss Resistance (Rfe)
Range:
Function:
10000.000
Ohm
*
[0 -
10000.000
Ohm]
Enter the equivalent iron loss
resistance (R
Fe
) value to
compensate for iron loss 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 P-36 Iron Loss Resistance (Rfe)
on default setting.
P-37 d-axis Inductance (Ld)
Range:
Function:
0 mH
*
[0.000 -
1000.000 mH]
Enter the value of the d-axis
inductance. Obtain the value from the
permanent magnet motor data sheet.
The d-axis inductance cannot be found
by performing an Auto Tune.
P-46 Position Detection Gain
Range:
Function:
100 %
*
[20 - 200 %] Adjusts the amplitude of the test pulse
during position detection at start. Adjust
this parameter to improve the position
measurement.
