4 Faults and alarms
4.2 List of faults and alarms
Remedy: - set the enable signals or check the cause of the fault that first occurred and then result (for a standard assignment).
- check the assignment to enable the basic positioning function.
Reaction upon N: NONE
Acknowl. upon N: NONE
F07491 (A) EPOS: STOP cam minus reached
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None
Reaction: OFF3
Acknowledge: IMMEDIATELY
Cause: A 0 signal was detected at binector input BI: p2569, i.e. the STOP cam minus was reached.
For a positive traversing direction, the STOP cam minus was reached - i.e. the wiring of the STOP cam is incorrect.
Remedy: - leave the STOP cam minus in the positive traversing direction and return the axis to the valid traversing range.
- check the wiring of the STOP cam.
Reaction upon A: NONE
Acknowl. upon A: NONE
F07492 (A) EPOS: STOP cam plus reached
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None
Reaction: OFF3
Acknowledge: IMMEDIATELY
Cause: A 0 signal was detected at binector input BI: p2570, i.e. the STOP cam plus was reached.
For a negative traversing direction, the STOP cam plus was reached - i.e. the wiring of the STOP cam is incorrect.
Remedy: - leave the STOP cam plus in the negative traversing direction and return the axis to the valid traversing range.
- check the wiring of the STOP cam.
Reaction upon A: NONE
Acknowl. upon A: NONE
F07493 LR: Overflow of the value range for position actual value
Message value: %1
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The value range (-2147483648 ... 2147483647) for the position actual value representation was exceeded.
When the overflow occurs, the "referenced" or "adjustment absolute measuring system" status is reset.
Fault value (r0949, interpret decimal):
1: The position actual value (r2521) has exceeded the value range.
2: The encoder position actual value Gn_XIST2 (r0483) or the absolute value after the load gear (r2723) has
exceeded the value range.
3: The maximum encoder value times the factor to convert the absolute position (r0483 and/or r2723) from
increments to length units (LU) has exceeded the value range for displaying the position actual value.
Note:
For a linear encoder, the following must be maintained:
- p0407 * p2503 / (2^p0418*10^7) < 1
- p0407 * p2503 / (2^p0419*10^7) < 1
Remedy: If required, reduce the traversing range or position resolution (p2506).
Increase the fine resolution of absolute position actual value (p0419).
