NCU link connection to all other NCUs of the link network has been
aborted
Definitions:
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 network. 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.
Reaction:
NC not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
Check the IPO cycle on all the NCUs.
If necessary, check NCU link-specific alarms first.
Program
Continuation:
Switch control OFF - ON.
28001
NCU link connection to the NCU %1 of the link network has been aborted
Parameters:
%1 = NCU number
Definitions:
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 network. (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.
Reaction:
NC not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
- Check the IPO cycle on all the NCUs.
- If necessary, check NCU link-specific alarms first.
Program
Continuation:
Switch control OFF - ON.
28002
Error on activation of machine data, NCU network-wide machine data
were modified by NCU %1
Parameters:
%1 = NCU number
Definitions:
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.
Reaction:
NC not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
Repeat the operator action or, if NEWCONFIG is activated by an NC program, terminate the program
with Reset.
Program
Continuation:
Clear alarm with the RESET key. Restart part program
