NOTE!
If one of the settings in parameter group 1-2* Motor Data
is changed, the advanced motor parameters,
to
, will return to default
setting.
This parameter cannot be adjusted while the motor is
running.
NOTE!
Full AMA should be run without filter only while reduced
AMA should be run with filter.
1-30 Stator Resistance (Rs)
Range:

*
[ 0.0 -
99.99 Ohm]
Set the stator resistance value. Enter
the value from a motor data sheet or
perform an AMA on a cold motor.
This parameter cannot be adjusted
while the motor is running.
1-33 Stator Leakage Reactance (X1)
Range:
Function:
Size related
*
[ 0.0 - 999.9 Ohm] Set stator leakage reactance of
motor.

*
[ 0.0 -
999.9
Ohm]
Set the main reactance of the motor using
one of these methods:
1.
Run an AMA on a cold motor. The
adjustable frequency drive 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
adjustable frequency drive
establishes the setting on the
basis of the motor nameplate
data.
NOTE!
This parameter cannot be adjusted while running.
1-37 d-axis Inductance (Ld)
Range:
Function:

*
[ 0 - 1000 ] Obtain the value from the permanent
magnet motor data sheet. The d-axis
inductance cannot be found by
performing an AMA.

Table 3.3
The table shows the number of poles for normal
speed ranges of various motor types. Define
motors designed for other frequencies separately.
The motor pole value is always an even number,
because it refers to the total number of poles, not
pairs of poles.
This parameter cannot be adjusted while the
motor is running.
