4.1.4 Parameters that cannot be changed during operation

For safety, the following parameters are designed so that they cannot be changed when the inverter is in operation. So, you need to stop the motor in advance to change these parameters.

[Basic parameters]

	(Automatic acceleration/deceleration)
	(Automatic V/f mode setting)
	(Operation command mode selection)
	(Speed setting mode selection)
	(Maximum frequency)
	(Standard setting mode selection)
	(Motor control mode selection)
	(Selection of electronic thermal protection characteristics)

For the parameter used to write-protect of extended parameters during operation, refer to Parameter list in 10.

4.1.5Resetting all parameters to the factory default settings at a time

All changed parameters can be reset to their respective factory default settings at a time by setting the standard setting mode selection parameter at .

Note) Refer to 5.5 for details of the standard setting mode selection parameter .

Note on operation

Setting the parameter  at  causes all parameters to return to the factory default settings. Therefore, it is advisable to note all changed settings before returning them to the default settings.

■Procedure for resetting all parameters to the factory default settings at a time

Key operated		LED display	Operation
			The operation frequency is displayed. (Make this setting
			when the motor is out of operation.)
	MON		Press the [MON] key to call up the first basic parameter
			(automatic acceleration/deceleration).
▲	▼		Switch to  by pressing △ or ▽ key.
	ENT		Press the Enter key to display the parameter setting (set
			value). ("" is always displayed when the parameter
			 is called up.)
▲	▼		Change the parameter setting by pressing △ or ▽
			key. To return all parameters to the factory default
			settings, change the parameter setting to .
	ENT		 is displayed while all parameters are being
			reset to their respective default settings.
			The LED returns to the original display mode.

If you feel puzzled about what to do next during this operation, press the Monitor key several times to return to the step  and follow the above steps all over again.
