9.6 Example: Change manual tools
Programming
In MD22562: $MC_TOOL_CHANGE_ERROR_MODE bit 1=1, additional tools without
magazine allocation have been selected by the NC part program. The selected tool must be
inserted in the machine manually and removed again manually after machining ("manual
tools").
The
operator
must
ensure
that the data block for the tool on the spindle is in the NCK, or that
he/she puts the appropriate tool onto the spindle for the data block stored in the NCK.
Note
The
responsibility
is
on
the user to comply with the safety regulations via the PLC user program.
The PLC user program is informed with DB43xx.DBX1.5 and DBX1.6 whether a manual tool
is involved in a tool change job. The operator receives a prompt to carry out the tool change:
17212 "Channel %1: Tool management:
Load manual tool %3, duplo No. %2 to tool holder %4
17214 "Channel %1: Tool management: Remove manual tool %3 from spindle / tool holder
%2"
The alarms are reset after a tool change by the acknowledgment from the PLC.
Starting position 1
The manual tool in the spindle should be exchanged for another manual tool.
Job from tool management to the PLC user program (tool change):
