4 Faults and alarms
4.2 List of faults and alarms
F07492 (A)
EPOS: STOP cam plus reached
Message class:
Application/technological function faulted (17)
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.
See also: p2570 (EPOS STOP cam plus)
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.
F07493
LR: Overflow of the value range for position actual value
Message class:
Application/technological function faulted (17)
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).
Note for fault value = 3:
If the value for the maximum possible absolute position (LU) is greater than 4294967296, then it is not possible to
make an adjustment due to an overflow.
For rotary encoders, the maximum possible absolute position (LU) is calculated as follows:
1. Motor encoder
p2506 * p2505 / p2504
p2506 * p2505 * p0421 / p2504 for multiturn encoders
2. Direct encoder
p2506
p2506 * p0421 for multiturn encoders
F07494
LR: Drive Data Set changeover in operation
Message class:
Application/technological function faulted (17)
Reaction:
OFF1 (OFF2, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
A Drive Data Set changeover (DDS) with a change of the mechanical relationships (p2503 ... 2506), direction of
rotation (p1821) or the encoder assignment (p2502) was requested in operation.
Note:
DDS: Drive Data Set
Remedy:
To changeover the drive data set, initially, exit the "operation" mode.
