Cause:
The value range (-2147483648 ... 2147483647) for the position actual value representation was exceeded.
When the overflow occurs, the "homed" 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 has exceeded the value range.
3: The maximum encoder value times the factor to convert the absolute position Gn_XIST2 from increments to length units
(LU) has exceeded the value range for displaying the position actual value.
Remedy:
If required, reduce the traversing range or position resolution (p2506).
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:
p2506 * p2505 / p2504
p2506 * p2505 * p0421 / p2504 for multiturn encoders

LR: Drive Data Set changeover in operation
Message class:
Application/technological function faulted (17)
Message value:
-
Component:
None
Response:
OFF1
Acknowledgment: 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.

LR: Homing function interrupted
Message class:
Application/technological function faulted (17)
Message value:
-
Component:
None
Response:
NONE
Acknowledgment: NONE
Cause:
An activated homing function (homing mark search or measuring probe evaluation) was canceled.
Possible causes:
- An encoder fault has occurred (Gn_ZSW.15 = 1).
- Position actual value was set during an activated homing function.
- Homing mark search and measuring probe evaluation simultaneously activated.
- Activated homing function (homing mark search or measuring probe evaluation) was de-activated.
Remedy:
- Check the causes and resolve.
- Reset the control and activate the required function.
