Channel %1 PLC acknowledge for command %2 is missing
%1 = Channel ID
%2 = Command no.
There is still no acknowledgement from the PLC for the tool change. The NCK cannot
continue processing until it receives this acknowledgement for the specified command
number. Possible command number values are described for alarm 6405.
- Alarm display.
- Interface signals are set.
- NC Start disable in this channel.
Please inform the authorized personnel/service department.
• Erroneous PLC communication: Correct the PLC program.
• It is possible to release NCK with the PLC command 7 from the wait condition.
This aborts the waiting command.
Clear alarm with the RESET key. Restart part program
Channel %1 tool %2 cannot be placed in magazine %3 on location %4. Invalid defi-
nition of magazine!
%1 = Channel ID
%2 = String (identifier)
%3 = Magazine number
%4 = Magazine location number
A tool change request or a verification 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!
- Alarm display.
- Interface signals are set.
- NC Start disable in this channel.
- NC Stop on alarm.
• Check whether the magazine data are correctly defined (especially the location type).
• Check whether the tool data are correctly defined (especially the location type).
Clear alarm with the RESET key. Restart part program
TO unit %1 tool %2 / Duplo no. %3 has reached its prewarning limit with D = %4
%1 = TO unit
%2 = Tool identifier (name)
%3 = Duplo number
%4 = D number
Tool monitoring: This message informs that the specified D offset has reached its pre-
warning limit for a time-, quantity- or wear-monitored tool. If possible, the D number is dis-
played; if not, value 0 is assigned to the 4th parameter.
If the function additive offset is being used, additive offset monitoring may be active
instead of tool wear monitoring. The actual type of tool monitoring is a tool property (see
$TC TP9). If replacement tools are not being used, the duplo number specified has no
meaning. The alarm is triggered through the MMC or PLC (=OPI interface). The channel
context is not defined. The TO unit was specified for this reason (see
$MC_MM_LINK_TOA_UNIT).
- Alarm display.
- Interface signals are set.
