Basic Control Operation
Chapter 2
2-23
After powering up the control or performing a control reset operation (see
page 2-4), the control assumes a number of initial operating conditions.
These are listed below:
Initial Password Access is assigned to the level that was active when
power was turned off (provided that level is a power-up level selected in
access control). If the active level when power is turned off is not a
power-up level, then the control defaults to the next lower level that is a
power-up level. See page 2-25 on access control.
The control is placed in E-Stop. The control is not allowed to come out
of E-Stop if the default AMP is loaded at power-up, or if there is no
PAL program loaded in the system. An appropriate error message is
displayed.
The control defaults to one G-code from each of these groups
(as set in AMP):
Modal Group: G-code
1 G00 Rapid traverse
G01 Linear interpolation
2 G17 Plane Selected
G18 Plane Selected
G19 Plane Selected
3 G90 Absolute
G91 Incremental
4 G22 Programmable Zone 2 and 3 (On)
G22.1 Programmable Zone 2 (Off) 3 (On)
G23 Programmable Zone 2 and 3 (Off)
G23.1 Programmable Zone 2 (On) 3 (Off)
5 G94 Feed per minute
G95 Feed per revolution
6* G70 Inch mode
G71 Metric mode
18 G07 Radius Programming Mode
G08 Diameter Programming Mode
* This G code group is only established at power up. A control reset
will not change the last programmed state of this modal G code group.
To show the current operating conditions at any time, access the G-code
status screen as described in chapter 8. If you do this immediately after
power-up, it shows the initial operating conditions selected in AMP along
with other control power-up default conditions.
