Up to eight M functions can be programmed for the activation or deactivation of the tool-specific
functions. Definition is realized using the following machine data:
MD52281 $MCS_TOOL_MCODE_FUNC_ON[0...3] M code for tool-specific function ON
= - 1
MD52282 $MCS_TOOL_MCODE_FUNC_OFF[0...3] M code for tool-specific function OFF
= - 1
The M functions for the tool-specific functions are executed by the ShopMill cycles at the tool
change. If the checkbox
is activated, the corresponding M code is generated from MD52281.
If the checkbox is not activated, the corresponding M code is generated from MD52282.
If you do not want to automatically execute additional M commands at the tool change, then
set the associated machine data to -1 for the M commands of this tool-specific function. This
also hides the associated fields in the tool list.
The default value of the machine data is -1 so that no M values are output for the corresponding
functions.
Technical procedure
The M functions for the tool-specific functions are generated by the ShopMill cycles in a set
(up to four M commands are possible).
The number and also the sequence of the M commands are dependent on the settings of the
machine data (MD52281 to MD52282) and the programming.
If M functions less than 100 are used, the number and sequence of the M commands has no
significance. They are located in the user PLC in the decoded area (DB250x.DBB1000 to
DB250x.DBB1012), independent of the number and the sequence when programming.
However, if M functions from 100 and higher are used, then you must decode these yourself
in the user PLC. In this case, you must take into consideration the number and sequence (M
function 1 to M function 4).
JOG mode
In the JOG mode, no coolant and tool-specific functions are output to the interface. For a tool
change in the JOG mode, these functions can be initiated by the operator using the keys on
the machine control panel (implementation via the PLC user program).
Example: Machine data settings
MD52281 $MCS_TOOL_MCODE_FUNC_ON[0] = 90
MD52281 $MCS_TOOL_MCODE_FUNC_ON[1] = 92
MD52281 $MCS_TOOL_MCODE_FUNC_ON[2] = 94
MD52281 $MCS_TOOL_MCODE_FUNC_ON[3] = 96
