Chapter 8 Motor Parameter Self-identification
8.1 Motor Parameter Self-identification
When the vector control mode is selected, the motor parameters must be self-identified.
For non-vector control, it is recommended to perform parameter self-identification during
the first run in order to improve the control accuracy.
The motor parameters required for calculation in vector control are usually not
available to users. The A90 series inverter has the function of motor parameter
self-identification. When the self-identification is enabled, the inverter will automatically
test the relevant parameters of the connected motor and store them into the internal memory.
Fig. 0-1 shows the specific meanings of the parameters of the three-phase asynchronous
motor.

R1, R2, L1, L2, Lm, and I0 in the figure represent: stator resistance, rotor resistance,
stator self-inductance, rotor self-inductance, mutual inductance, and no-load excitation
current. The leakage inductance is Ls=L-Lm.
8.2 Precautions before Self-identification
Motor parameter self-identification is a process of automatically measuring motor
parameters. The A90 series inverter can perform the static and rotary
self-identification of motor parameters.
The static self-identification is applicable when the motor load cannot be removed
but the motor parameters are available.
