- Alarm display.
- Interface signals are set.
- NC not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
Check the IPO cycle on all the NCUs.
If necessary, check NCU link-specific alarms first.
Switch control OFF - ON.
NCU link connection to the NCU %1 of the link network has been aborted
%1 = NCU number
All NCUs in the NCU link network exchange data cyclically (sign-of-life). If this alarm
occurs, sign-of-life signals have not been received from one other NCU on the NCU net-
work. (see alarm parameters) This fault in the link can have various causes:
• Defective hardware.
• 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.
- Alarm display.
- Interface signals are set.
- NC not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
• Check the IPO cycle on all the NCUs.
• If necessary, check NCU link-specific alarms first.
Switch control OFF - ON.
Error on activation of machine data, NCU network-wide machine data were modi-
fied by NCU %1
%1 = NCU number
During the activation of machine data with NEWCONFIG or during an operator panel
RESET, NCU network-wide machine data were modified on another NCU. This alarm can
only occur when a link connection is active.
- Alarm display.
- Interface signals are set.
- NC not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
Repeat the operator action or, if NEWCONFIG is activated by an NC program, terminate
the program with Reset.
Clear alarm with the RESET key. Restart part program
NCU link: NCU %1 of the link network is not on the bus
%1 = NCU number
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 on the bus although it should be connected according to the MD settings.
This fault in the link can have various causes:
• Defective hardware.
• 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.
