Stabilization Parameter
•This function adjusts to reduce motor hunting.
•In case of motor hunting, check whether motor capacity H003/H203 and motor pole number
selection H004/H204 match your motor. If they do not, match them. If the motor's primary
resistance is smaller than that of the standard motor, increase the H006/H206/H306 set value
gradually. To run a motor with a capacity larger than the Inverter's rated capacity, reduce the set
value.
•Other than this function, the following methods are suggested to reduce hunting:
Lower the carrier frequency (b083). (Refer to page 4-65.)
Lower the output voltage gain (A045). (Refer to page 4-24.)
