Tool management
Because of the axis disable, the assignment of a tool magazine is not changed during
program testing. A PLC application must be used to ensure that the integrity of the data in
the tool management system and the magazine is not corrupted. The toolbox diskettes
contain an example of the basic PLC program.
2.4.2
Program execution in singleblock mode
Functionality
The part program can be started via interface signal:
DB21, ... DBX7.1 (NC Start).
When the "Single block" function is activated, the part program stops executing after every
program block. If tool cutter radius compensation or a tool nose radius correction is selected,
processing stops after every intermediate block inserted by the control.
The program status switches to "Program status stopped".
The channel status remains active.
The next part program block is processed on NC Start.
Usage
The user can execute a part program block-by-block to check the individual machining steps.
Once the user decides that an executed part program block is functioning correctly, he can
call the next block. This is done by triggering NC Start.
Basic logic functions: Mode group, channel, program operation, reset response (K1)
