Pm Motor Control And Starting Torque Optimization Setting - Toshiba TOSVERT VF-AS3 Instruction Manual

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.
<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.
<F912: PM q-axis inductance>
<F913: PM d-axis inductance>
Set q-axis inductance and d-axis inductance (mH) of PM motor.
Use values measured by LCR meters, etc.
• To use PM motor control, the motor capacity must be the same as the inverter rated capacity, or
Memo
you can use a motor with capacity no less than one rank below.

■ 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.

Title Parameter name
F915 PM control method
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".
1: Method 1
This value sets initial position estimation for high saliency motors.
2: Method 2
This value sets initial position estimation and starting torque optimization for high saliency
motors.
