6.25.2 Setting motor constants for PM motors
f400 : Auto-tuning
f462 : Speed reference filter
f402 : Automatic torque boost value coefficient
f405 : Motor rated capacity
f912 : q-axis inductance
f415 : Motor rated current f913 : d-axis inductance
f417 : Motor rated speed
f459 : Load inertia moment ratio
Caution:
If the settings for V/F control mode selections pt is 6: vector control for PM motor
Look at the motor's name plate and set the following parameters.
vl: Base frequency 1 (rated frequency) that is calculated from Back EMF
vlv: Base frequency voltage 1 (rated voltage) that is calculated from Back EMF
f405: Motor rated capacity
f415: Motor rated current
f417: Motor rated speed
f912: Q axis inductance per phase
f913: D axis inductance per phase
[Selection 1: Setting PM motor control and auto-tuning]
After setting pt =6, auto-tuning occurs.
Set the auto-tuning parameter f400 to 2 (Auto-tuning enabled)
