3.3.4 1-3* Adv. Motor Data
Parameters for advanced motor data. The motor data in par. 1-30
to run the motor optimally. The default settings are figures based on common motor parameter values from 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
the moment of inertia of the rotor and the iron loss resistance (par. 1-36
Par. 1-3* and par. 1-4* cannot be adjusted while the motor is running.

Iron Loss Resistance (Rfe)
Function:
Set the stator resistance value. Enter the value from a motor data sheet or perform an AMA on a
cold motor.
Function:
Fine-tuning R will improve shaft performance. Set the rotor resistance value using one of these
r
methods:
1. Run an AMA on a cold motor. The frequency converter will measure the value from the
motor. All compensations are reset to 100%.
2. Enter the R value manually. Obtain the value from the motor supplier.

Function:
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
