Toshiba VF-A7 instruction manual Factory default setting  = , Trip clear  = 

[ Factory default setting (  =  ) ]

Setting  at  returns all parameters to their respective default settings.

When this parameter is set at 3,

to the original display (  history records.



or 

is displayed for a while, then switches back

). Note that this setting also clears all trouble

[ Trip clear (  =  ) ]

Setting  at  clears the oldest 4 trip history records. (This setting does not change any parameter settings.)

[ Clearing accumulating operation time (  =  ) ]

Setting  at  clears the cumulative operation time (resets it to zero).

[ Initialization of type form information (  =  ) ]

When a trip occurs because of a type error ( is displayed), you can clear the trip by setting  at . This function is used to reformat a control circuit board to adapt it to an inverter, for example, when a circuit board is removed from an inverter to use for another inverter for maintenance or for other reasons. This setting clears all type data stored in the inverter.

[ Memorization of user-defined parameters ( =  ) ]

Setting  at  causes all the current parameter settings to be stored individually.

[ Reset of user-defined parameters (  =  ) ]

Setting  at  returns all parameters to the settings saved by setting this parameter at .

The above settings  and  allows you to have your own default parameter settings.
