Stabilized factor
When the motor is hunting or unstable, this function can be adjusted to
help stabilize the motor.
When the motor is unstable, check the allowable motor selection (H003/H203) and motor pole selection
(H004/H204) with your motor. If their code data is different from your motor specification, set the right data.
When R1 of usage motor is less than R1 of regular motor, raise the set value of H006/H206 gradually.
When you operate greater motor than rated capacity of inverter, lower the set value of H006/H206.
The following two functions can also assist to reduce hunting or rattling of a motor.
(1) Lower the carrier frequency (b083).
(2) Lower the output voltage gain (A045).

Operation selection on option error
When an add-in option is the cause of a protective trip this
function can be used to switch the trip facility off and allow
the Inverter to carry on in it’s operation.

Motor constant
Set each constant according to the motor you use.
In case of using several motors in parallel, set the constant
values that are closest to the total capacity of the belonging motor.
Reduced torque or instability may occur while using auto torque boost function if these settings are incorrect.
