Default setting values are set so that the moment of inertia of the load (including the motor
shaft) value is set to be appropriate at 100% of the motor shaft. If the moment of inertia of the
load is not 100%, set a value appropriate for the actual moment of inertia of the load.
<F460: Speed control response 1>
<F461: Speed control stabilization coefficient 1>
<F462: Speed reference filter coefficient 1>
<F463: Speed control response 2>
<F464: Speed control stabilization coefficient 2>
<F465: Speed reference filter coefficient 2>
<F466: Speed control response switching frequency>
This parameter adjusts the excess response speed.
Increasing this value will reduce the overshoot at the acceleration/deceleration completion
point. Set a value appropriate for the actual moment of inertia of the load.
For details, refer to "Current and Speed Control Gain Adjustment Method" manual (E6582136).
<F912: PM q-axis inductance>
<F913: PM d-axis inductance>
Set q-axis inductance and d-axis inductance (mH) of PM motor.
Use <F400: auto-tuning> to set the value.
■ PM motor control and starting torque optimization setting
If the PM motor does not start after auto-tuning due to heavy load, set <F915: PM control method>
to "4" for starting torque optimization.
6) Parameter setting
7) How to select setting values
0: Method 0
This value sets no initial position estimation control. Reverse run may occur at startup.
If tripping occurs with PM auto-tuning error "E-39", use this function by setting <F915> to "0".
Memo
• To use PM motor control, the motor capacity must be the same as the inverter rated capacity, or
you can use a motor with capacity no less than one rank below.
• If there is a possibility that main power supply is shut down during running, set <F301: Auto-
restart> to activate.
Otherwise, when DC-bus voltage is recovered and inverter start to run again, E-39 or OP trip
occurs, because motor is still rotated and back EMF voltage is high.
