A variety of tool types can be called from the machining program. The
abbreviations below are defined for the following examples:
N: Tool for which one pocket is defined in the tool table (Normal)
M: Tool for which no pocket number is defined in the tool table. You must
change the tool manually (Manual).
S: Special tool, definition in the tool table
There are nine possible combinations in the tool-change sequence. For some
sequences it is necessary during TOOL CALL to output two pocket or tool
numbers in sequence. You can see in M4520 if another tool or pocket number
is transferred. The sequence of transfers for tool and pocket numbers can be
defined in two manners:
Define the sequence in MP7481.x. In this case set M4540 = 0.
Define the sequence in M4540. In this case set MP7481.x = %00000000.
You must evaluate and acknowledge both pocket or tool numbers. As an
alternative, all of this information can be found with Module 9035.
