Ohm]
Set the line-to-common stator
resistance value. Enter the value
from a motor datasheet or perform
an AMA on a cold motor.
NOTICE
For salient PM motors:
AMA is not available.
If only line-line data is
available, divide the line-line
value by 2 to achieve the line-
to-common (star point) value.
Alternatively, measure the
value with an ohmmeter. This
also takes the resistance of the
cable into account. Divide the
measured value by 2 and enter
the result.
NOTICE
The parameter value is
updated after each torque
calibration if option

start with store
or option

Every start with store
is

1-31 Rotor Resistance (Rr)
Range:
Function:
Set the rotor resistance value R
r
to
improve shaft performance using 1
of these methods:
•
Run an AMA on a cold
motor. The frequency
converter measures the
value from the motor. All
compensations are reset
to 100%.
•
Enter the R
r
value
manually. Obtain the value
from the motor supplier.
•
Use the R
r
default setting.
The frequency converter
establishes the setting
based on the motor
nameplate data.

Set the stator leakage reactance of
the motor using 1 of these
methods:
•
Run an AMA on a cold
motor. The frequency
converter measures the
value from the motor.
