Basic Control Operation
Chapter 2
2-33
The control provides 3 basic operation modes:
manual (MAN or MANUAL)
manual data input (MDI)
automatic (AUTO)
You can select a mode by using
<MODE SELECT>
on the MTB panel, or
using the
{FRONT PANEL}
softkey. This is configurable by your system
installer. Both means of selection cannot be available. Details on using
the
{FRONT PANEL}
softkey are given on page 2-15.
Depending on the current control status, a mode change request cannot be
honored. Operating modes may not be changed if any of these are true:
The control is in E-Stop.
The control is in the cycle-suspend state. This results when a program
is halted during the execution of a block.
The control is executing a threading- or multiple-pass turning cycle.
Important: Your system installer may have written PAL to disable the use
of the
{FRONT PANEL}
softkey to change modes. If this is the case, then
changing modes can be performed by using only
<MODE SELECT>
on the
MTB panel.
