A30650(1000): Reference and actual checksum in monitoring channel 2 are not identical (booting).
- as a result of the changed current controller sampling time (p0115[0]), the clock cycle time for the Safety Integrated Basic Functions (r9880) was adapted.
- safety parameters set offline and loaded into the Control Unit.
- a download was made to the SINAMICS, whose firmware versions in monitoring channel 2 did not correspond to the latest version. The request to switch off the DRIVE-CLiQ component A1007 was present after the download.
- at least one checksum-checked piece of data is defective.
