The locked state is set when a value is set in the parameter PASSWD.
However, note that parameter PASSWD can be set only when the locked
state is not set (when PASSWD = 0, or PASSWD = KEYWD). If an
attempt is made to set parameter PASSWD in other cases, a warning is
given to indicate that writing is disabled. When the locked state is set
(when PASSWD = 0 and PASSWD = KEYWD), parameter NE9 is
automatically set to 1. If an attempt is made to set NE9 to 0, a warning
is given to indicate that writing is disabled.
Parameter PASSWD can be changed when the locked state is released
(when PASSWD = 0, or PASSWD = KEYWD). After step 3 in the
procedure for unlocking, a new value can be set in the parameter
PASSWD. From that time on, this new value must be set in parameter
KEYWD to release the locked state.
When 0 is set in the parameter PASSWD, the number 0 is displayed, and
the password function is disabled. In other words, the password function
can be disabled by either not setting parameter PASSWD at all, or by
setting 0 in parameter PASSWD after step 3 of the procedure for
unlocking. To ensure that the locked state is not entered, care must be
taken not to set a value other than 0 in parameter PASSWD.
After the locked state has been released, it can be set again by setting a
different value in parameter PASSWD, or by turning the power to the NC
off then on again to reset parameter KEYWD.
CAUTION
Once the locked state is set, parameter NE9 cannot be set
to 0 and parameter PASSWD cannot be changed until the
locked state is released or the memory all–clear operation
is performed. Special care must be taken in setting
parameter PASSWD.
