Fault History Display Method
Fault description is displayed when U09 is selected.
(Example)
: Fault description
“---” is displayed if there is no fault.
(Refer to page 97 for details.)
Clearing the Fault History
Set constant n01 to 6 to clear the fault history. Set data returns to its initial value after 6 is set.
Note: Initializing the constants (n01=8, 9) also clears the fault history.

Simple Data Setting
Digital setting (refer to 5. Operating the Inverter ) and potentiometer setting are both possible for simple acceleration/deceleration operation of the VS mini.
Frequency reference by potentiometer signal is set with initial setting
(n03=0).
Factory setting of the model with operator (without potentiometer) is set by Digital Operator (n03=1).
