Corrected from:
Servo-Inverter i950 FW V01.05.02.1788
(Update via EASY Package-Manager)
Response of the new version:
An absolute target position (0x503F/71 = Absolute Positioning [2] ) is approached correctly after the reference search has been completed.
What happens?
If the homing function (0x6060 = Homing [6] ) is used in the TA CiA402 Advanced and an absolute position is to be approached after the reference position has been detected (0x503F/71 = Absolute Positioning [2] ), it may happen that the drive does not stop at the target position but rotates endlessly in one direction.
When does the behaviour occur?
- Using the homing functionality of the TA CiA402 Advanced (0x6060 = Homing [6])
- Homing mode (0x6098/0) is not equal to SetPositionDirect [0]
- Reference position (0x607C) is 0 or near zero
- After the reference search has been completed, an absolute position is to be approached (0x503F/71 = Absolute Positioning [2] )

Short-term measures, Evaluation/Recommendations:
- Do not use the option 0x503F/71 = Absolute Positioning [2].
- If a defined target is to be approached after the reference search, this can also be done relatively (0x503F/71 = Relative Positioning [1] ). The distance in 0x503F/72 must then be adjusted accordingly.
