Stabilization Parameter - Omron SYSDRIVE MX SERIES User Manual

Stabilization Parameter

•This function adjusts to reduce motor hunting.
•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.
•Other than this function, the following methods are suggested to reduce hunting:
•Lower the carrier frequency (b083)
•Lower the output voltage gain (A045)
