5) Motor parameter setting method (Basic)
<F401: Slip frequency gain>
This parameter sets the compensation gain for motor slip.
Increasing the value will reduce motor slip.
Set <F417: Motor rated speed> and then make fine adjustments to <F401>.
Keep in mind that setting a higher value than necessary will cause unstable operation such as
hunting.
<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.
<F412: Leakage inductance>
This parameter sets the leakage inductance component of the motor.
Increasing this value will improve torque in the high-speed region.
<F415: Motor rated current>
This parameter sets the motor rated current.
Check the motor name plate or test report while setting.
<F416: Motor no load current>
This parameter sets the ratio of the motor no-load current to the rated current.
This is equivalent to the exciting inductance of the motor.
Check the no-load current value in the motor test report and divide it by the rated current value.
Set the calculated value in %.
