Operating the Control
2-23
To reset the emergency stop state, press the <E-STOP RESET> button. Once
you push the E--Stop Reset button to clear the E--Stop state, the message,
“RESETTING E--STOP” displays to alert you that the control is attempting
to come out of E--Stop. After the cause of the E--Stop is resolved, the
control clears the “E--STOP” message. If the error condition is not cleared,
the “RESETTING E--STOP” message clears, but the “E--STOP” message
continues to flash as the control remains in E--Stop state.
If the E-Stop occurred during program execution, the control resets the
program when you perform an E-Stop reset (provided AMP is configured
to perform a control reset or E-Stop reset). Assuming that you perform a
control reset, program execution begins from the 1st block of the program
when you press
<CYCLE START> . If the current axis position prohibits this,
the operator can manually jog the axes clear, or consider executing a
mid-program start (see page 7-13). If you do not perform a control reset or
E-Stop reset, the control aborts the remainder of the program block being
executed when E-Stop took place, and a
<CYCLE START> begins program
execution at the next block.
Important: If you do not eliminate the cause of the E-Stop, the circuit
connected to the E-STOP STATUS terminals on the sub-basic board
remains open, and the emergency stop state is not reset even when you
press the
<E-STOP RESET> button.
Reciprocation stops when an emergency stop condition occurs. No motion
occurs when the emergency stop is reset. If your control’s AMP is
configured such that the control is not reset after an E-Stop reset, then
typically reciprocation resumes with the next cycle start. This allows part
programs to be resumed immediately without having to first restart
reciprocation. For details, see the documentation prepared by your system
installer.
Access control lets your system installer assign different functions of the
control to different users by means of a password. See page 2-28 for a list
of the functions that can be protected on the control.
Each protectable function is assigned an access level that is made active
when the operator enters his 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. You can assign a total of 8 passwords.
Important: If you do not want to use password protection, 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. You can also disable password
