(3) Entering password
When an attempt is made to write a parameter on the editing screen for parameters related to the safety
monitoring function, the screen for entering the password appears.
Enter a correct password and press the [OK] button to write the parameter to the controller. If the password is
incorrect, writing the parameter is not executed. After the error dialog is displayed, the screen for entering
passwords appears again.
Entering passwords is required for the first attempt to write a parameter after the editing screen for
parameters related to the safety monitoring function is displayed. When writing parameters is continued
without closing the editing screen for parameters related to the safety monitoring function, it is not necessary
to enter the password again.
4-18 Startup
If you forget the password, parameters related to the safety monitoring function cannot
be changed. Never forget the registered password. If you forgot the password, the
memory in the controller needs to be initialized to the factory default setting by robot type
resetting operation. For details about the robot type resetting operation, refer to the
"Instruction manual/Detailed explanations of functions and operations" supplied with the
robot arm.
To prevent unintended change of parameters, keep passwords in a secure place without
leakage of the invention to a third party.
