1566 HEIDENHAIN Technical Manual iTNC 530 HSCI
With Modules 9092, 9350 (9093), 9351 (9094) and 9096 you can read the tool
and pocket tables and overwrite them.
The operating system cyclically saves tables to the hard disk approximately
every five seconds. In case of a power failure, the control automatically blocks
access to the hard disk, in order to protect it from damage. If tables or table
contents are changed, and the rare case of a power failure occurs within the
next five seconds before the next automatic saving, the last changes can be
lost. Should this cause problems on your machines, then more frequent saving
of tables can be forced by setting MP4020 bit 15. If MP4020 bit 15 = 1, then
tables are saved each time they are closed. However, if tables are changed
very frequently (e.g. via PLC program or submit job), then this can have a
negative effect on the computing performance, since the number of accesses
to the hard disk would increase significantly.
If an input field is open in the editor at the time the modules are called, this
field is closed automatically.
The status display shows the current tool data.
With MP7263 bit 1 you configure the output of the column in the pocket table
during backup and during conversion from binary format to ASCII.
By setting MP7263 bit 2, the "Edit ON/OFF" soft key can be hidden when the
pocket table is displayed. This makes it possible to prevent manual editing of
the pocket table.
MP7263 bit 3 can be used to hide the RESET POCKET TABLE and RESET
COLUMN T soft keys.
MP7260 to MP7267 can also be overwritten by the PLC or the LSV2 protocol.
The bits 4, 5 and 6 of machine parameter MP7263 are used to define
settings for deleting tools and their index entries. These settings apply to
tools in the pocket table.
During control start-up the prototype pocket table (PLC:\PROTO\PROTOTYP.TCH)
is used when a pocket table is created. The standard pocket table is only
created if no prototype pocket table exists.
If bit 12 is set in MP7682, the error message "Tool radius too large" is
suppressed if R2 > R for a tool in the tool table. This might be necessary if
barrel cutters are used. Please keep in mind that the cutter form
compensation with LN blocks does not work with this cutter shape.
