$MN_MM_CC_MD_MEM_SIZE.
Program Con-
tinuation:
Switch control OFF - ON.
6401 Channel %1 tool change not possible: Empty location for tool %2 Duplo no. %3 on
magazine %4 not available.
Parameters: %1 = Channel ID
%2 = String (identifier)
%3 = Duplonummer
%4 = Magazine number
Definitions: The tool cannot be moved into the selected tool magazine. There is no appropriate loca-
tion for this tool. A suitable location is mainly determined by the status. The status must
indicate that this location is free, not disabled, not reserved and not co-occupied by a tool
that is too large. Furthermore, it is important that the type of tool matches the type of any
magazine location that may be free. (If, for example, all magazine locations are of the 'B'
type and these are all free and the tool is of type 'A', then this tool cannot be put into this
magazine).
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: • Check whether the magazine data have been defined correctly.
• Check whether there is still room in the magazine to add another tool; there may not be
due to operating procedures.
• Check whether a location type hierarchy is defined and whether it, for example, does not
allow insertion of a type 'A' tool in a free location with type 'B'.
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
