Basic Control Operation

Chapter 2

2-23

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

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 page 7-12. If no control reset is performed, the remainder of the

program block being executed when E-Stop took place is aborted, and a

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

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.
