2) Unlock
Enter a password in [Pr. 297].
The lock is unlocked when a password is correct.
If a password is incorrect, an error occurs and the
lock is not unlocked.
During [Pr. 296 = "101 to 106"], if password unlock
error has occurred 5 times, correct password will
not unlock the restriction. (During password lock)
(3) Parameter operation during password lock/unlock
Parameter write is restricted as the following during password lock.

*1 Reading/writing is unavailable when there is restriction to reading by the [Pr. 160] setting.
*2 Unavailable during operation of voltage output.
*3 Correct password will not unlock the restriction.
When [Pr. 296 = "4, 5, 104, 105" ] and using the
parameter unit
operation is unavailable. When writing is restricted
from PU mode operation command [ Pr. 296 = 1, 2, 4,
5, 101, 102, 104, 105 ], switching of operation mode
by easy setting mode is unavailable.
2.18.6 Free parameter [Pr. 888, 889]
You can input any number within the setting range 0 to
9999.
For example, the parameter can be used:
• As a unit number when multiple units are used.
• As a pattern number for each operation application
when multiple units are used.
• As the year and month of introduction or inspection.
[Pr. 888, Pr. 889] do not influence the inverter operation.

parameter all clear to unlock the parameter
restriction. In that case,
also cleared. (All parameter clear cannot be
performed during operation.)
