Detailed Description
2.2 Mode groups
The chosen machine function TEACH IN, REPOS, or REF
is activated in:

Operating statuses
The following three channel statuses can occur in each mode:
1. Channel reset
2. Channel active
3. Channel interrupted
Functions in the modes
Operating modes are supplemented through userspecific functions. These functions are not
related to any particular technology or machine. A subset of the available functions can be
selected in each mode, depending on the operating state.
These functions are categorized as follows:
• NCKspecific functions
• Mode groupspecific functions
• Channel-specific functions
The individual functions can be started and/or executed from the three individual channel
statuses: channel reset, channel active, or channel interrupted. The channel states and
program states can be checked on the operator panel.
Boundary condition for submode TEACH IN
TEACH IN is not permissible for leading or following axes of an active axis grouping, e.g.,
for:
• Gantry axis grouping or a gantry axis pair
• Coupled-axis grouping of master and slave axis

The machine is in its initial state. This is defined by the machine manufacturer's PLC

A program has been started, and the program is being executed or a reference point
approach is in progress.
The running program or reference point approach has been interrupted.
