A07441 LR: Save the position offset of the absolute encoder adjustment
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: NONE
Acknowledge: NONE
Cause: The status of the absolute encoder adjustment has changed.
In order to permanently save the determined position offset (p2525) it must be saved in a non-volatile fashion (p0971,
p0977).
Remedy: Not necessary.
This alarm automatically disappears after the offset has been saved.

F07442 (A) LR: Multiturn does not match the modulo range
Message value: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The ratio between the multiturn resolution and the modulo range (p2576) is not an integer number.
This results in the adjustment being set back, as the position actual value cannot be reproduced after power-
off/power-on.
Remedy: Make the ration between the multiturn resolution and the modulo range an integer number.
The ratio v is calculated as follows:
1. Motor encoder without position tracking:
v = (p0421 * p2506 * p0433 * p2505) / (p0432 * p2504 * p2576)
2. Motor encoder with position tracking for the measuring gear:
v = (p0412 * p2506 * p2505) / (p2504 * p2576)
3. Motor encoder with position tracking for the load gear:
v = (p2721 * p2506 * p0433) / (p0432 * p2576)
4. Motor encoder with position tracking for the load and measuring gear:
v = (p2721 * p2506) / p2576
5. Direct encoder without position tracking:
v = (p0421 * p2506 * p0433) / (p0432 * p2576)
6. Direct encoder with position tracking for the measuring gear:
v = (p0412 * p2506) / p2576
Note:
With position tracking, it is recommended that p0412 and p2721 are changed

F07443 (A) LR: Reference point coordinate not in the permissible range
Message value: %1
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The reference point coordinate received when adjusting the encoder via connector input p2599 lies outside the half
of the encoder range and cannot be set as actual axis position.
Fault value (r0949, decimal interpretation):
Maximum permissible value for the reference point coordinate.
Remedy: Set the reference point coordinate to a lower value than specified in the fault value.
