7.18.2 Tool magazine management
The following must be borne in mind when doing a tool change:
• The tool change is not validated until the execution of the T function or M06 is completed correctly.
If it is not completed correctly, the tool magazine table is not refreshed.
• If while executing a T or M06 function something unexpected happens, (CNC error, PLC error;
e-stop button pressed, CNC reset, etc.) a mark (TMINEM) will be activated that will set 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 memorizes this error until it is canceled
by a PLC mark (RESTMEM) or by the option [REMOVE ERROR] that appears in the error
message.
If this error is not canceled as mentioned earlier, it will stay memorized even if the CNC is turned
off and back on repeatedly. Even if the magazine error is memorized, the machine can keep
working.
The CNC will only show this error message if the user requests a new tool while the error situation
is unsolved (PLC mark TMINEM active). The magazine error only prevents a new tool change.
In the conversational mode, it will show the error: "Tool magazine in error state".
In ISO mode, in MANUAL (JOG), MDI or AUTO, it shows the error: "Emergency in tool magazine".
• During the state error, 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 be disabled.
This management is only possible when a tool magazine has been defined.
Example of a PLC program to manage the emergencies at 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
;
TOOL 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.
