What are default values of stator resistance, inductance and rotor time constant RSA, LFA, TRA in Altivar ATV320 variable speed drive?
There are no default values of RSA, LFA, or TRA in the drive. These values depend on motor data that are entered. NPR (rated motor power), ULN (rated motor voltage), NCR (nominal current), and NSP (nominal speed) are those parameters that have an impact on RSA, LFA, TRA.
As soon as you enter these data, values RSA, LFA, TRA will be changed. These changed values will be considered by the motor control algorithm unless autotuning is executed.
Autotuning will overwrite RSA. LFA, TRA by new values that are measured by the drive.
