<Group H: Motor Control Parameters>
Motor Capacity and Pole Number
Set the capacity and number of poles of the motor connected to the Inverter.
•With incorrect parameters set, appropriate operation cannot be ensured.
* To switch to the 2nd control, allocate 08 (SET) to the multi-function input terminal and then turn it on.
Stabilization Parameter
This function helps to reduce motor hunting.
* To switch to the 2nd control, allocate 08 (SET) to the multi-function input terminal and then turn it on.
•In case of motor hunting, check whether the motor capacity selection (H003/H203) and motor pole
number selection (H004/H204) match your motor. If they do not, match them.
•For adjustment, raise the stabilization parameter (H006) by degrees. If this increases motor
hunting, lower it by degrees.
•When using the automatic torque boost (A041/A241 = 01), if motor hunting occurs in a low speed
range, lower the manual torque boost voltage (A042/A242) and manual torque boost frequency
(A043/A243).
•Other than this function, the following methods are suggested to reduce hunting:
Lower the carrier frequency (b083)
Lower the output voltage gain (A045)
