Overview of Alarms
SINAMICS-Alarms
207460 <location>EPOS: End of reference cam not found
Message -
value:
Drive object: SERVO, VECTOR
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: 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" (BI: p2612).
Maximum traversing range: -2147483648 [LU] ... -2147483647 [LU]
Remedy: - check the "reference cam" binector input (BI: p2612).
- repeat the search for reference.
See also: p2612 (EPOS search for reference, reference cam)
207461 <location>EPOS: Reference point not set
Message -
value:
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: When starting a traversing block/direct setpoint input, a reference point is not set (r2684.11 = 0).
Remedy: Reference the system (search for reference, flying referencing, set reference point).
207462 <location>EPOS: Selected traversing block number does not exist
Message %1
value:
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: A traversing block selected via BI: p2625 to BI: p2630 was started via BI: p2631 = 0/1 edge "Activate
traversing task".
- the number of the started traversing block is not contained in p2616[0...n].
- the started traversing block is suppressed.
Alarm value (r2124, interpret decimal):
Number of the selected traversing block that is also not available.
Remedy: - correct the traversing program.
- select an available traversing block number.
207463 <location>EPOS: External block change not requested in the traversing
block
Message %1
value:
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: 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: Resolve the reason as to why the edge is missing at binector input (BI: p2632).
207464 <location>EPOS: Traversing block is inconsistent
Message %1
value:
Drive object: SERVO, VECTOR
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
