Trip 0 (L29) to Trip 9 (L38) store the most recent 10 trips that have occurred where Trip 0 (L29) is the most recent and Trip 9 (L38) is the oldest. When
a new trip occurs it is written to Trip 0 (L29) and all the other trips move down the log, with oldest being lost. The date and time when each trip occurs
are also stored in the date and time log, i.e. Trip 0 Date (L41) to Trip 9 Time (L60). The date and time are taken from Date (J80) and Time (J81).
Some trips have sub-trip numbers which give more detail about the reason for the trip. If a trip has a sub-trip number its value is stored in the sub-trip
log, i.e. Trip 0 Sub Trip Number (L61) to Trip 9 Sub Trip Number (L70). If the trip does not have a sub-trip number then zero is stored in the sub-trip
log.
Trip categories and priorities
Trips are grouped into the categories given in the table below. A trip can only occur when the drive is not tripped, or if it is already tripped and the new
trip has a higher priority than the active trip (i.e. lower priority number). Unless otherwise stated a trip cannot be reset until 1.0 s after it has been
initiated.

These are fatal problems that cannot be reset. All drive features
are inactive after any of these trips occur. If a basic keypad is
installed it will show the trip, but the keypad will not function.
These trips are not stored in the trip log.
This trip cannot be cleared unless 1299 is entered into
Pr mm00 and a reset is initiated.
,
These trips cannot be reset.
This can only be reset if Pr mm00 is set to 1233 or 1244, or if
Default Drive (H04) is set to a non-zero value.
This trip can override Encoder 2 to Encoder 6 trips.
These trips cannot be reset until 10s after the trip was initiated.
The drive will attempt to stop the motor before tripping if a
Phase Loss.000 trip occurs unless this feature has been
disabled (see Action On Trip Detection (H45). The drive will
always attempt to stop the motor before tripping if an OHt dc
bus occurs.
