Table41: Parameters for automatic motor adaptation for asynchronous motors
Parameter Description Possible settings Factory setting
3-3-3-1 Start Automatic Motor Adaptation
Function used to start automatic motor
adaptation (AMA).
1. Offline calculation: Using the nominal
data of the motor as a basis, the
extended motor data is calculated.
2. Standard AMA: The extended motor
data is determined by taking a
measurement with the motor being at
a standstill.
3. Extended AMA: The extended motor
data is determined by taking a
measurement with the motor running
at approximately 10percent of its
nominal speed.
▪ Extended AMA – Motor

▪ Standard AMA – Motor at
Standstill

3-3-3-2 Rs Motor Stator Phase Resistance
Extended motor data:
Stator phase resistance
0,0...5000,000 Dependent on motor
3-3-3-3 LS – Motor Stator Phase Inductance
Extended motor data: Stator phase
inductance
0,0...5000,0 Dependent on motor
3-3-3-4 TR – Rotor Time Constant
Extended motor data: Rotor time constant
0,0...5000,0 Dependent on motor
3-3-3-5 Km – Magnetisation Coefficient of Stator
and Rotor
Extended motor data: The magnetisation
coefficient describes the magnetic coupling
between the stator and rotor of the motor.
0,0000 ... 100,0000 Dependent on motor
8.5.2 Automatic motor adaptation (AMA) of frequency inverter for KSB SuPremE
motors
Automatic motor adaptation for the KSB SuPremE motor is started using the Update
Motor Parameters (3-3-4-1) parameter. Using the nominal motor data as a basis, the
extended motor data is determined which ensures very good control of the KSB
SuPremE motor.

3-3-4-1 Update Motor Parameters
Function used to start automatic motor
adaptation (AMA) for the KSB SuPremE
motor.
Using the nominal motor data as a basis,
the extended motor data is determined
which ensures very good control of the
KSB SuPremE motor.
