Display	Meaning	Corrective Actions
	Function Selection Error
OPE08	A setting has been made that is applicable with the cur-
	rent control method.	Verify the control method and the function.
Constant Selection
	Example: A function used only with open loop vector
	control was selected for V/f control.
OPE010	V/f Parameter Setting Error	Check parameters (E1-††). A frequency/voltage value
V/f Ptrn Setting		may be set higher than the maximum frequency/voltage.

‹Autotuning Faults

Autotuning faults are shown below. When the following faults are detected, the fault is displayed on the digital operator and the motor coasts to stop. No fault or alarm outputs will be operated.
