Fault
Cause
Remedy
F7459: Zero mark not detect-
ed
Reaction: OFF1
Acknowledgement:
IMMEDIATELY
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.
• 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)
F7460: EPOS: End of refer-
ence cam not found
Reaction: OFF1 (OFF2,
OFF3)
Acknowledgement:
IMMEDIATELY
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]
• Check the "reference cam" input.
• Repeat the search for reference.
F7464: EPOS: Traversing
block is inconsistent
Reaction: OFF1 (OFF2,
OFF3)
Acknowledgement:
IMMEDIATELY
The traversing block does not contain vaild
information.
Alarm value:
Number of the traversing block with invaild
information.
Check the traversing block and where rele-
vant, take into consideration alarms that are
present.
F7475: EPOS: Target posi-
tion < start of traversing
range
Reaction: OFF1 (OFF2,
OFF3)
Acknowledgement:
IMMEDIATELY
The target position for relative traversing
lies outside the traversing range.
Correct the target position.
F7476: EPOS: Target posi-
tion > end of the traversing
range
Reaction: OFF1 (OFF2,
OFF3)
Acknowledgement:
IMMEDIATELY
The target position for relative traversing
lies outside the traversing range.
Correct the target position.
F7481: EPOS: Axis position <
software limit switch minus
Reaction: OFF1 (OFF2,
OFF3)
Acknowledgement:
IMMEDIATELY
The actual position of the axis is less than
the position of the software limit switch
minus.
• Correct the target position.
• Change software limit switch minus (CI:
p2580).
F7482: EPOS: Axis position >
software limit switch plus
Reaction: OFF1 (OFF2,
OFF3)
Acknowledgement:
IMMEDIATELY
The actual position of the axis is greater
than the position of the software limit
switch plus.
• Correct the target position.
• Change software limit switch plus (CI:
p2581).
