NCU link connection to all other NCUs of the link network has been aborted
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 any other NCUs on the NCU net-
work. This fault in the link can have various causes:
• Defective hardware.
• The machine data which configure the NCU link are not the same on all NCUs.
• An identical interpolator cycle time has not been selected on all NCUs.
- NC not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- 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.
- NC not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- 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.
- NC not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- 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
