Rs, L
If/Tr/Ls are tuned continuously except Encoder Test
Rs Tuning
Rs tuning Only. The stator resistance is tuned at standstill.
Lsigma
L
tuning Only. The Leakage Inductance is tuned at standstill.
If/Tr/Ls Tune
Finds If/Tr/Ls by applying DC current pulse. It finds magnetizing current, secondary
constant of motor and first inductance concurrently.
Inertia Tuning
It finds Inertial constant after operating motor to forward/reverse operation with one third
base speed.
FWD/REV LEDs are blinking during auto-tuning.
