Basic Control Operation
Chapter 2
2-25
If the E-Stop occurred during program execution, the control may reset the
program when E-Stop reset is performed provided AMP is configured to
do so. Assuming that a control reset is performed, program execution
begins from the first block of the program when
<CYCLE START> is
pressed. If the current axis position prohibits this, the operator can
manually jog the axes clear, or consider executing a Mid-Program Start.
See chapter 7. If no control reset is performed, the remainder of the
program block being executed when E-Stop took place is aborted, and a
<CYCLE START> begins program execution at the next block.
Important: If the cause of the E-Stop is not eliminated, the circuit
connected to the E-STOP STATUS terminals remains open, and the
emergency stop state is not reset even when the
<E-STOP RESET> button is
pressed.
Access control lets the system installer assign different functions of the
control to different users by means of a password. See section 2.7.2 for a
list of the functions that may be protected on the 9/Series control.
Each protectable function is assigned an access level that is made active
when the operator enters the password. When an access level is made
active, all functions that are assigned to that access level become available.
Access levels range between 1 and 8 where 1 is the highest level and 8 is
the lowest. A different password is assigned to each of the different access
levels. Eight passwords can be assigned.
Access control only applies to the front panel and softkey inputs. It cannot
control inputs from outside the system. For instance, if you control access
to the delete function, the user can’t delete a file, but a file can be deleted
by Mini-DNC software and by Data Highway with the 9/Series Data
Highway Plus Communication Module.
Important: If you do not want to use password protection, simply select
all functions as accessible for access level 8. Since access level 8 is
automatically available at power up, no password is necessary to access
any of the functions of the control. Password protection can also be
disabled by assigning a level at the power-up level by using the
“POWER UP LEVEL” parameter as described in section 2.7.2.
