Cause
An error has occurred during the position
actual value preprocessing.
After starting the search for reference, the
axis moved through the maximum permis-
sible distance to seach for the reference
cam without actually finding the reference
cam.
After leaving the reference cam, the axis
has traversed the maximum permissible
distance (p2609) between the reference
cam and the zero mark without finding the
zero mark.
During the search for reference, when the
axis reached the zero mark it also reached
the end of the traversing range without
detecting an edge at the binector input
"reference cam".
Maximum traversing range: -2147483648
[LU] ... -2147483647 [LU]
The traversing block does not contain vaild
information.
Alarm value:
Number of the traversing block with invaild
information.
12.2 List of faults and alarms
Remedy
Check the encoder for the position actual
value preprocessing.
Check the "reference cam" input.
•
Check the maximum permissible distance
•
to the reference cam (p2606).
See also: p2606 (EPOS search for reference
reference cam maximum distance)
Check the encoder regarding zero mark.
•
Check the maximum permissible distance
•
between the reference cam and zero mark
(p2609).
Use an external encoder zero mark (equi-
•
valent zero mark).
See also: p2609 (EPOS search for reference
max distance ref cam and zero mark)
Check the "reference cam" input.
•
Repeat the search for reference.
•
Check the traversing block and where rele-
vant, take into consideration alarms that are
present.
