<F405: Motor rated capacity>
<F415: Motor rated current>
<F417: Motor rated speed>
<F459: Load inertia ratio>
<F462: Speed reference filter coefficient 1>
<F465: Speed reference filter coefficient 2>

■ 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.
■ 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>
