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.
3.2.3 1-3* Adv. Motor Data
Parameters for advanced motor data. The motor data in
to
must match the
relevant motor in order to run the motor optimally. The
default settings are figures based on common motor
parameter values from normal standard motors. If the motor
parameters are not set correctly, a malfunction of the
frequency converter system may occur. If the motor data is
not known, running an AMA (Automatic Motor Adaptation)
is recommended. See the
Automatic Motor Adaptation
section. The AMA sequence will adjust all motor parameters.
1-30 Stator Resistance (Rs)
Range:
Function:
Size related
*
[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.
1-35 Main Reactance (Xh)
Range:

*
[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
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.
NOTE
This parameter cannot be adjusted while running.
1-39 Motor Poles

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.
3.2.4 1-4* Cable Length
1-42 Motor Cable Length
Range:
Function:
50.0 m

[0.0 - 150.0 m] Only effect on smaller drives.
Set the motor cable length during
commissioning
1-43 Motor Cable Length Feet
Range:
Function:
144 ft
*
[0 - 431 ft] Only effect on smaller drives.
Set the motor cable length during commis-
sioning

Use this parameter along with
to obtain a different
thermal load on the motor when running at low
speed.
Enter a value which is a percentage of the rated
magnetising current. If the setting is too low, the
torque on the motor shaft may be reduced.
