27900 PROFIBUS DP: SI fault on axis %1, code %2, value %3, time %4.
Parameters: %1 = Axis number
%2 = Fault code of the drive (r9747).
%3 = Fault value of the drive (r9749)
%4 = Fault time of drive (r9748).
Definitions: Error in a SINAMICS drive.
Reaction: Alarm display.
Remedy: See drive documentation for fault codes/fault values.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.

27901 PROFIBUS DP: SI fault on axis %1, code %2, value %3, time %4.
Parameters: %1 = Axis number
%2 = Fault code of the drive (r9747).
%3 = Fault value of the drive (r9749)
%4 = Fault time of drive (r9748).
Definitions: Error in a SINAMICS drive.
Reaction: Alarm display.
Remedy: See drive documentation for fault codes/fault values.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
28000 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 Con- Switch control OFF - ON.
tinuation:
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:

Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: - Check the IPO cycle on all the NCUs.
