4-2 Function Mode 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) 4 Functions FV/FI Adjustment You can adjust the FV/FI frequency input. Use this to change the full scale of input.
The set frequency becomes 0 Hz with 0.0% set. This returns to the factory default value after initialization. 4-34 Parameter No. Function name Data Description A045 Output voltage gain 20. to 100. Unit: % If hunting occurs, reduce the set value. b083 Carrier frequency 2.0 to 14.0 Unit: kHz If hunting occurs, reduce the set value. H006/H206 Stabilization parameter 0. to 255. If hunting occurs, adjust the set value. Function code Item Data Description C081 FV adjustment 0.0 to 200.0% Unit: % C082 FI adjustment 0.0 to 200.0% Unit:
