A07469 EPOS: Traversing block < target position < software limit switch minus
Reaction: NONE
Acknowledge: NONE
Cause: In the traversing block the specified absolute target position lies outside the range limited by the software limit switch
minus.
Alarm value (r2124, interpret decimal):
Number of the traversing block with illegal target position.
Remedy: - correct the traversing block.
- change software limit switch minus (CI: p2578, p2580).
A07470 EPOS: Traversing block> target position > software limit switch plus
Reaction: NONE
Acknowledge: NONE
Cause: In the traversing block the specified absolute target position lies outside the range limited by the software limit switch
plus.
Alarm value (r2124, interpret decimal):
Number of the traversing block with illegal target position.
Remedy: - correct the traversing block.
- change software limit switch plus (CI: p2579, p2581).
A07471 EPOS: Traversing block target position outside the modulo range
Reaction: NONE
Acknowledge: NONE
Cause: In the traversing block the target position lies outside the modulo range.
Alarm value (r2124, interpret decimal):
Number of the traversing block with illegal target position.
Remedy: - in the traversing block, correct the target position.
- change the modulo range (p2576).
A07472 EPOS: Traversing block ABS_POS/ABS_NEG not possible
Reaction: NONE
Acknowledge: NONE
Cause: In the traversing block the positioning mode ABS_POS or ABS_NEG were parameterized with the modulo correction
not activated.
Alarm value (r2124, interpret decimal):
Number of the traversing block with the illegal positioning mode.
Remedy: Correct the traversing block.
A07473 (F) EPOS: Beginning of traversing range reached
Reaction: NONE
Acknowledge: NONE
Cause: When traversing, the axis has moved to the traversing range limit.
Remedy: Move away in the positive direction.
A07474 (F) EPOS: End of traversing range reached
Reaction: NONE
Acknowledge: NONE
Cause: When traversing, the axis has moved to the traversing range limit.
Remedy: Move away in the negative direction.
F07475 (A) EPOS: Target position < start of traversing range
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The target position for relative traversing lies outside the traversing range.
Remedy: Correct the target position.
