zero value, the value is the user password. The password takes effect after you after exit the
function code editing state. When you press
again, "------" will be displayed, and you
must enter the correct user password to enter the menu.
To cancel the password protection function, enter with password and set FP-00 to 0.
4.18 Parameter Saving and Default Setting Restoring
After a function code is modied on the operation panel, the modication will be saved in the
register of the AC drive and remain effective at next power-on.
The AC drive supports backup and restoration of parameter setting, which is convenient for
commissioning.
The AC drive also provides the retentive function on alarm information and accumulative
running time.
You can restore the backup values or default settings of the function codes of the AC drive
or clear the running data through FP-01. For details, see the description of FP-01.
