5) Motor parameter setting method
<F402: Automatic torque boost>
This parameter adjusts the primary resistive component of the motor.
Increasing this value will prevent torque reduction due to voltage drop during low speed.
Adjust the value according to the actual operation. Keep in mind that setting a higher value
than necessary will increase current at low speed and may cause tripping.
If there is a motor test report, check the stator resistance value per phase.
<F402> (%) = (√3 x Rs x <F415> x 0.9) / (Vtype x 100)
where Rs is the stator resistance value per phase (Ω), Vtype is 200, 400 V (depends on voltage
class).
<F405: Motor rated capacity>
This parameter sets the motor rated capacity.
Check the motor name plate or test report while setting.
<F415: Motor rated current>
This parameter sets the motor rated current.
Check the motor name plate or test report while setting.
<F417: Motor rated speed>
This parameter sets the motor rated speed.
Check the motor name plate or test report while setting.
How to adjust the moment of inertia of the load
<F459: Load inertia ratio>
This parameter adjusts the excess response speed.
Increasing this value will reduce the overshoot at the acceleration/deceleration completion
point.
