H Password Setting (Fn010)
• This function prevents the user parameter settings and System Check Mode settings and adjustments
being overwritten unintentionally.
• When a write-prohibited password is set, from the next power-up onwards it becomes impossible to
make parameter settings or to make settings or adjustments in System Check Mode. It still remains
possible, however, to refer to the user parameters and perform some functions in System Check
Mode. The functions that can be performed in System Check Mode while write prohibited is enabled
are as follows:
Display alarm log (Fn000), password setting (Fn010), Servomotor parameters check (Fn011), and
version check (Fn012).
If you try to perform any functions other than these, “nO OP” will flash for approximately 1 s, and then the
display will return to the function code.
• If you set the write-enabled password, the write-prohibited status will be cancelled (i.e., you can write
to the user parameters, etc., when the power is next turned ON again).
