â– Function
To select PM motor control with <Pt: V/f Pattern>, you must set motor parameters (auto-tuning).
There are three setting methods.
• Set <Pt> and <F400: Offline auto-tuning> individually.
• Set <Pt> and <F400> individually. Perform an auto-tuning after calculating the motor parameter
automatically (available with motor not connected).
• Set <Pt> and set the motor parameter manually.
â– Setting method 1: Set auto-tuning
Set PM motor control and auto-tuning individually.
First, set <Pt: V/f Pattern> to "6: PM motor control". For details of setting methods, refer to [5. 3. 4].
Next, perform offline auto-tuning.
Important
• To set <Pt: V/f Pattern> to "6: PM motor control" or "12: PG feedback PM motor control", check
the motor name plate and set the following parameters first.
 - <vL: Base frequency 1> (Rated frequency): calculate from back EMF
 - <vLv: Base frequency voltage 1> (Rated voltage): calculate from back EMF
 - <F405: Motor rated capacity>
 - <F415: Motor rated current>
 - <F417: Motor rated speed>
 - <F912: PM q-axis inductance>
 - <F913: PM d-axis inductance>
