The password function (bit 4 (NE9) of parameter No. 3202) can be locked
using parameter No. 3210 (PASSWD) and parameter No. 3211
(KEYWD) to protect program Nos. 9000 to 9999. In the locked state,
parameter NE9 cannot be set to 0. In this state, program Nos. 9000 to 9999
cannot be modified unless the correct keyword is set.
A locked state means that the value set in the parameter PASSWD differs
from the value set in the parameter KEYWD. The values set in these
parameters are not displayed. The locked state is released when the value
already set in the parameter PASSWD is also set in parameter KEYWD.
When 0 is displayed in parameter PASSWD, parameter PASSWD is not
set.
Procedure for locking and unlocking
1 Set the MDI mode.
2 Enable parameter writing. At this time, P/S alarm No. 100 is issued
on the CNC.
3 Set parameter No. 3210 (PASSWD). At this time, the locked state is
set.
4 Disable parameter writing.
5 Press the
RESET
key to release the alarm state.
1 Set the MDI mode.
2 Enable parameter writing. At this time, P/S alarm No. 100 is issued
on the CNC.
3 In parameter No. 3211 (KEYWD), set the same value as set in
parameter No. 3210 (PASSWD) for locking. At this time, the locked
state is released.
4 Set bit 4 (NE9) of parameter No. 3202 to 0.
5 Disable parameter writing.
6 Press the
RESET
key to release the alarm state.
7 Subprograms from program Nos. 9000 to 9999 can now be edited.
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.
