- NC Stop on alarm.
Remedy: Check the machine data configuration and link hardware.
Program Con- Switch control OFF - ON.
tinuation:
28005
NCU link: NCU %1 of the link network not running synchronously
Parameters: %1 = NCU number
Definitions: Error message of the NCU link module. When the NCU link was powered up, the local
NCU (indicated by the alarm) detected that the NCU with the number in the alarm param-
eter was not running synchronously.
This fault in the link can have various causes:
• The machine data which configure the NCU link are not identical on all NCUs.
• An identical interpolator cycle time has not been selected on all NCUs.
Reactions: - NC not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Check machine data configuration.
Program Con- Switch control OFF - ON.
tinuation:
28007
NCU link: conflict in configuration data of NCU %1
Parameters: %1 = NCU number
Definitions: Error message of the NCU link module. When the NCU link was powered up, the local
NCU (indicated by the alarm) detected a conflict between its configuration and the config-
uration of the NCU in the alarm parameter.
Example: Machine data LINK_NUM_OF_MODULES defines the number of nodes on the
NCU link network. The alarm occurs if this MD has a different setting on different NCUs.
Reactions: - NC not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Check machine data configuration.
Program Con- Switch control OFF - ON.
tinuation:
28008
NCU link: conflict in timer setting of NCU %1
Parameters: %1 = NCU number
Definitions: Error message of the NCU link module. When the NCU link was powered up, the local
NCU (indicated by the alarm) detected a conflict between its timer configuration and the
configuration of the NCU in the alarm parameter.
Reactions: - NC not ready.
- Channel not ready.
