Contains the last 10 drive trips. Pr 10.20 is the most recent trip and Pr 10.29 the oldest. When a new trip occurs all the parameters move down one,
the current trip is put in Pr 10.20 and the oldest trip is lost from the bottom of the log. Descriptions of the trips are given in the table below. All trips are
stored, including HF trips numbered from 20 to 29. (HF trips with numbers from 1 to 16 are not stored in the trip log.) Any trip can be initiated by the
actions described or by writing the relevant trip number to Pr 10.38. If any trips shown as user trips are initiated the trip string is "txxx", where xxx is
the trip number.
