Special "Warning" status
"Warning" is a special status (independent, "orthogonal" state), which does not influence the
operational performance of the machine module.
• Possible states:
...active: "Warning" (or: ...not active: "No Warning")
9.3.2 Initial state of the state transitions
The state transitions between the module state machine and the module applications are in the
initial state as follows:
By means of methods, the state transitions can be influenced (enable/inhibit).
...
User-defined
Mode 1...2
User-definable states
• ... depend on the application of the respective machine
Homing In the "Homing" state, the drive is referenced. Either the home
position is set directly, or a homing process is started.
...
Upcoming
error states
May occur at any time.
• A machine module, machine modules of the same hierarchy level,
or subordinated slaves can cause errors.
• The module application cannot inhibit the state transitions when
the error status occurs.
• By programming the machine modules, the response to an error
status can be defined.
