Remedy: - Check whether the tool status 'is being changed' ('H20') is set. If yes, then the appropriate tool
change command must first be completed by the PLC. Then the tool should be able to be moved.
- Check whether the tool data are correctly defined. Has the correct T number been specified?
- Check whether the move command has been correctly parameterized. Is the desired tool at the
source location? Is the target location suitable for taking the tool?
- Check whether the tool has already been loaded (if the alarm occurs while loading the tool).
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
6425 [Channel %1: ] Tool %2 cannot be placed in magazine %3 on location %4.
Invalid definition of magazine!
Parameters: %1 = Channel ID
%2 = String (identifier)
%3 = Magazine number
%4 = Magazine location number
Definitions: The desired tool motion command - triggered from the MMC or PLC - is not possible. A movement
request was issued to put the tool in a location which does not satisfy the prerequisites for filling.
The following causes for the error are possible:
- Location is blocked or not free!
- Tool type does not match the location type!
- Tool possibly too large, adjacent locations are not free!
- If a tool is to be loaded or unloaded, the load/unload position must be of 'load location' type.
- If a tool is to be loaded or unloaded, is the magazine in question linked to the load/unload location?
