What does 108 mean?
The checksum read from the drive's analog calibration data does not match the checksum calculated. This indicates a corruption in the internal calibration data, which affects the accuracy of analog signal processing. The drive requires a hardware replacement to resolve this internal data inconsistency.
Common Causes
- Checksum error detected during analog input calibration data verification.
- Corrupted calibration data in drive memory.
- Incorrect calibration procedure performed.
- Analog input sensor drift causing calibration failure.
