1-31 Rotor Resistance (Rr)
Range: Function:
Size re-
lated
[Ohm] Fine-tuning R
r
will improve shaft performance. Set the rotor re-
sistance value using one of these methods:
1. Run an AMA on a cold motor. The frequency converter
will measure the value from the motor. All compensa-
tions 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 name-
plate data.
1-33 Stator Leakage Reactance (X1)
Range: Function:
Size re-
lated
[Ohm] Set the stator leakage 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
1
value manually. Obtain the value from the
motor supplier.
3. Use the X
1
default setting. The frequency converter
establishes the setting on the basis of the motor name
plate data.
1-34 Rotor Leakage Reactance (X2)
Option: Function:
[Size re-
lated]
Ohm Set the rotor leakage 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
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.
1-35 Main Reactance (Xh)
Option: Function:
[Size re-
lated]
Ohm Set the main reactance of the motor using one of these meth-
ods:
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.
