9.5 Example: Loading/unloading
Programming
For loading, tools are placed directly in the magazine or the spindle; for unloading, they are
removed
directly
from
the
magazine. Normally, a single acknowledgment from the operator or
the PLC user program (tool holder is closed again) is sufficient as a message that the process
is complete. There is no need to configure a transfer step. The total acknowledgment can be
set in DB40xx.DBX0.0.

Loading procedures using handling systems or transporting the tool from the spindle into the
magazine can be performed using further asynchronous messages.
Note
Manual tools
Please observe the special issues when using manual tools (Page 257).
A tool that was loaded into the spindle or a magazine, is not a manual tool. As a consequence,
it is placed in the magazine using T0/M06.
Additional loading processes are described in the following sections.
Loading via the spindle with preselection of a magazine location
You can create a new tool directly on the chosen free magazine location or, using the "load"
dialog, move a tool from the tool list, which is not located in the magazine, to a magazine
location.
1. A job from the
tool management is always output at the interface for the loading point. You
must acknowledge this job.
2. Then move the tool, which is not yet located in the magazine, into the spindle using Txx
M6 or via an asynchronous transfer.
3. Then manually place the tool into the spindle and deposit it in the magazine with T0 M6.
