HEIDENHAIN iTNC 530 HSCI - Output of the Pocket Number with Variable Pocket Coding

1612 HEIDENHAIN Technical Manual iTNC 530 HSCI
Output of the
pocket number
with variable
pocket coding
With variable pocket coding (MP7480.x = 3 or 4) the pocket number of the
called tool is transferred to the PLC and the assignment of tool and pocket
number is changed in the pocket table. The current tool number is additionally
saved in W264. The NC takes over responsibility for variable pocket
management.
If you have set M4542, the assignment of tool and pocket numbers in the
pocket table does not change, although variable pocket coding was selected.
You set this marker, for example, during a block scan (except if
MP7681 bit 1=1).
 In MP7261, enter the number of tools with pocket number. The maximum
input value is the number of the pockets in the tool magazine.
In the tool table you can define more tools than can be held by the tool
magazine (MP7260 > MP7261). If a tool number is programmed for which no
pocket was defined, during a TOOL CALL the pocket number –1 (W262) is
transferred and M4523 is set.
During programming of TOOL DEF the tool and pocket numbers are transferred.
A TOOL DEF for a manual tool has no relevance for the PLC.
Define in the column F a fixed pocket. If a fixed pocket has been defined for a
tool, it will be returned to its original pocket in spite of the variable pocket
coding.
