A.1 List of important alarms and faults
Number Cause
F07840 The "Infeed operation" signal is not available, though
the enables for the drive have already been pending
for longer than the parameterized monitoring time
(p0857).
Infeed not in operation.
•
Interconnection of the binector input for the 'ready'
•
signal is incorrect or missing (p0864).
Infeed is currently identifying the network.
•
A08526 No cyclic connection to the control is available.
56
Remedy
Put infeed into operation.
•
Check the interconnection of the binector input for
•
the "infeed operation" signal (p0864).
Extend monitoring time (p0857).
•
Wait for completion of the infeed network identifi-
•
cation.
Establish a cyclic connection and activate the control
with cyclic operation.
On PROFINET, check the parameters "Name of sta-
tion" and "IP of station" (r61000, r61001).
If a CBE20 is inserted and PROFIBUS should com-
municate through process data interface 1, then this
has to be parameterized with the STARTER commis-
sioning tool or directly through p8839.
