5.14.2 Tool change management
When doing a tool change, the following must be considered:
• The tool change is not validated until function T or M06 is completely and successfully executed.
If it is not successfully executed, the magazine table will not be refreshed.
• If anything (a CNC error, PLC error, E-stop button pressed, CNC reset, etc.) happens while
executing a T or M6 function, a mark (TMINEM) will be activated setting the CNC in an error state.
• When executing a tool change, O1 must be set =1 in the tool change operation of the PLC
program. Otherwise, the CNC will issue the error message "tool magazine in error state".
• If an error is detected during a tool change, the CNC saves this error until it is canceled by a
PLC mark (RESTMEM) or using the [REMOVE ERROR] option that appears in the error
message.
If this error is not cancelled as described earlier, it will stay in memory even if the CNC is powered
down and back up several times. Even if the magazine error is memorized, the machine can keep
on working.
The CNC will only show this error if the user requests a new tool while the CNC's error state
has not been solved. The magazine error only prevents a new tool change.
• During the error state, it is possible to execute any instruction in any mode (Jog, MDI) or even
execute a program.
Only the execution of any T or M6 will not be possible.
This will be managed only if a tool magazine has been defined.
Example of a PLC program to manage the emergencies in the tool magazine:
;
TMINEM ;Tool magazine manager in emergency state
= MSG100 ;Message to "check magazine and execute M98"
;
DFU TMINEM ;Tool magazine manager in emergency state
= RES SETTMEM ;Set the magazine manager in emergency state
;
M_SUBM06 ;Indicates tool changing subroutine. (M06) in
execution
AND NOT TMINEM ;Tool magazine manager in emergency state
AND (NOT M_POTENCIA ;Power-on and CNC-PLC OK
OR M_M06ERROR ;An error occurs when executing M06
OR RESETOUT) ;CNC reset
= SET SETTMEM ;Set the magazine manager in emergency state
;
DFU SETTMEM ;Set the magazine manager in emergency state
OR DFU TMINEM ;Tool magazine manager in emergency state
= ERA M1007 1010 ;Initialize magazine management related marks
=RES M_SUBM06 ;Tool change subroutine. (M06) in execution
;
M98 ;Confirm magazine checked with M98
AND TMINEM ;Tool magazine manager in emergency state
= SET RESTMEM ;Reset the emergency request to the manager
;
MAGAZINE IN ERROR STATE
Before removing the error, check that the position of the tools in the
magazine and the active tool match the tool table.
