Operating Instructions, 04/2017, A5E37208830-003
Cause
An illegal combination of input signals that
are simultaneously set was identified.
Alarm value (r2124, interpret decimal):
0: Jog 1 and jog 2.
1: Jog 1 or jog 2 and direct setpoint in-
put/MDI.
2: Jog 1 or jog 2 and start referencing.
3: Jog 1 or jog 2 and activate traversing
task.
4: Direct setpoint input/MDI and starting
referencing.
5: Direct setpoint input/MDI and activate
traversing task.
6: Start referencing and activate traversing
task.
When starting a traversing block/direct
setpoint input, a reference point is not set.
A traversing block selected via PROFINET
control words POS_STW1.0 to
POS_STW1.5 (when telegram 111 is
used) or SATZANW.0 to SATZANW.5
(when telegram 7, 9 and 110 are used)
was started via PROFINET control word
STW1.6 = 0/1 edge "Activate traversing
task".
The selected traversing block exceeds
•
the block number limit, relevant high-
order bits should remain low. Refer to
Section "Traversing blocks"
The started traversing block is sup-
•
pressed.
Alarm value (r2124, interpret decimal):
Number of the selected traversing block
that is also not vailable.
For a traversing block with the block
change enable
CONTINUE_EXTERNAL_ALARM, the
external block change was not requested.
Alarm value (r2124, interpret decimal):
Number of the traversing block.

Remedy
Check the appropriate input signals and cor-
rect.
Reference the system (search for reference,
flying referencing, set reference point).
Correct the traversing program.
•
Select an available traversing block num-
•
ber.
Resolve the reason as to why the edge is
missing at STW1.13.
