TOOL_MANAGEMENT_MASK
Channel–specific activation of tool management
Min. input limit: 0
Protection level: 2/4
MD = 0: Tool management inactive
Bit 0=1: Tool management active
The tool management functions are
enabled for the current channel.
Bit 1=1: Tool monitoring function active
Functions that are used for tool monitoring (tool life and
workpiece count) are enabled.
Bit 2=1: OEM functions active
The memory can be used for user data
(see also MD 18090 to 18098).
Bit 3=1: Considering the adjacent location active
Bit 0 to Bit 3 must be set as for MD 18080:
MM_TOOL_MANAGEMENT_MASK.
Bit 4=1: The PLC is able to request another tool change preparation process with
modified parameters.
With T selection or M06 the part program pauses until acknowledged by the PLC
program
Bit 5=1: When the tool command is output the main run of the main spindle can be
stopped within one OB1 cycle (e.g. by read–in halt).
Bit 5=0: When the command is output to the PLC the main run of the main spindle is
resumed.
Bit 6=1: When the tool command is output the main run of the auxiliary spindle can be
stopped within one OB1 cycle (e.g. by read–in halt).
Bit 6=0: When the command is output to the PLC the main run of the main spindle is
resumed.
Bit 7=1: The main run of the main spindle is halted
until acknowledgment with status 1 is received via FC7, FC8.
Bit 7=0: When the command is output to the PLC the main run of the main spindle is
resumed.
Bit 8=1: The main run of the auxiliary spindle is halted until acknowledgment with
status 1 is received via FC7, FC8.
Bit 8=0: When the command is output to the PLC the main run of the auxiliary spindle is
resumed.
Bit 9: Reserved 10=1:
via FC8 (status 1) from the PLC.
The change signal (e.g. M06) is only output
when tool selection (DBX [ n+0 ].2) is acknowledged. The part program is
halted with M06 until tool selection is acknowledged.
Bit 10=0: The tool change ON command NCK –> PLC is not output until the PLC
preparation acknowledgment has been received. This is relevant for
PLC command 3 (i.e. programming of M06 in a
block containing no T).
Bit 11=1: The preparation command is output even if it has already been issued once for
the same tool.
This system is used to position the chain with the first '' Tx ''
and to check with the second call whether the tool is in the correct tool–change
location (e.g. in front of the changing station)
Bit 11=0: The preparation command can be output only once for a tool.
Bit 12=1: The preparation command is executed even if the tool is already in the spindle.
This means that the T selection signal (DB72.DBXn.2) is set
even if it has already been set once for the same tool. (Tx...Tx)
Bit 12=0: The preparation command is not executed if the tool is already inserted
in the spindle.
