Hello. I'm using Axis FB for the vertical axis. During commissioning time I ran into the problem with unexpected movement after axis dataset switching. At those moment Axis FB and Axis were enabled and stopped. After this, I tried switch ADS with disabled FB and Axis. In this case, an unexpected movement didn't happen but arose another problem with status Homed for ADS with the incremental encoder. It goes Off after the second command executePos (or executeMove). In the program, I use three ADS: one with incremental and two with the absolute encoders. Only full-power switching off of D425-2 module helps in this situation. Might anybody have any advice? Regards, Yury ------------------------------------------------------------------------------------------ |

Hello, Note If the active measuring system is switched via a data set changeover, the _setAndGetEncoderValue() system function should be used to synchronize the two measuring systems before the switchover takes place. This will prevent unwanted compensating movements of the position controller if differences in position are identified General info about data sets: 3.22 Data sets https://support.industry.siemens.com/cs/ww/en/view/109757317 |
