The M functions for the tool–specific functions are generated by the ShopMill
cycles in a single record (up to 4 M commands are possible). The number and
also the sequence of the M commands are dependent upon the machine data
settings (MD9739 – MD9746) and the programming.
With machine data setting "–1", no M command is issued for the corresponding
tool–specific function. The same applies if no entry (neither "on" nor "off") is
made during programming in the menu "Programs" –> "Line/circle" –> "Machine
functions".
If M functions smaller than 100 are used, the number and sequence of M com-
mands is irrelevant since they are available in the operator PLC in the decoded
area (DB21.DBB194 – DB21.DBB206), regardless of the number and he se-
quence during programming.
However, if M functions above 100 are used, they must be decoded in the oper-
ator PLC. In this case, the number and the sequence (M function 1 – M function
4) must be observed.
The display machine data are predefined so that no M values are output for the
corresponding functions. For example, only the "On" statuses can be output via
separate M commands and "Off" via a joint M command.
Machine data settings:
MD 9739 $MM_CMM_M_CODE_TOOL_1_ON : 90
MD 9740 $MM_CMM_M_CODE_TOOL_1_OFF : 91
MD 9741 $MM_CMM_M_CODE_TOOL_2_ON : 92
MD 9742 $MM_CMM_M_CODE_TOOL_2_OFF : –1
MD 9743 $MM_CMM_M_CODE_TOOL_3_ON : 94
MD 9744 $MM_CMM_M_CODE_TOOL_3_OFF : 95
MD 9745 $MM_CMM_M_CODE_TOOL_4_ON : 96
MD 9746 $MM_CMM_M_CODE_TOOL_4_OFF : 97
The following functions are programmed in the menu Programs" → "Line/circle"
→ "Machine functions".
Tool–specific function 1: on
Tool–specific function 2: off
Tool–specific function 3: not programmed
Tool–specific function 4 : off
The ShopMill interface generates the following M functions:
M90 M97
The fields in the tool list for displaying the tool–specific functions can be hidden
via settings of the respective machine data. If both M commands of a function
=–1, the corresponding field is not displayed on the interface.
In "MANUAL" mode, no spindle direction of rotation, coolant and tool–specific M
functions are output to the PLC. On tool change in the "MANUAL" mode, these
functions can be initiated by the operator using the keys on the machine control
panel (implementation via PLC user program).
You can change the cursor texts for "Coolant 1/2 on/off" and "Tool–spec. fct. 1,
..." (see Section 8.9 "Modifying Texts for Tool–specific Functions").
