Table 9-2 Sub-trip identification
9.6 Displaying trip history
The E300 Elevator drive stores all drive trips for diagnostics.
9.6.1 Trip log parameters
Trip log
Parameter Trip 0 (L29) through to Trip 9 (L38) store the 10 most recent trips that have occurred where Trip 0 (L29) is the most recent and Trip 9
(L38) is the oldest trip captured. When a new trip occurs and is captured it is written to Trip 0 (L29) and all the other trips move down the log, with
oldest being lost.
Sub trip numbers
Some trips have sub-trip numbers which provide more detail on the possible cause 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 will be stored in the
sub-trip log.
Table 9-3 Trip history parameters
Date and time
The date and time when each of the trips occur is stored in the date and time log for all trips from Trip 0 through to Trip 9. The format of the date and
time stamping is as follows. The date when each trip occurs is stored in Trip 0 Date (L41) and Trip 0 Time (L42) going through to Trip 9 Date (L59)
and Trip 9 Time (L60). The date and time are taken from Date (J80) and Time (J81).
• Date: date - month - year 31 - 12 - 99
• Time: hours : minutes : seconds 23 : 59 : 59
The date and time for the trip log can be selected as detailed in the following table
Table 9-4 Date and Time selector
When the Date, Time Selector = 0 the date and time can be written by the user, and the values are transferred to the real time clocks (RTC) in the
keypad or any option module that support this feature installed to the drive. When Date, Time Selector is changed to any other value, the real time
clocks are allowed to run normally again.
When Date, Time Selector is changed from any value to 0 the date and time from a real time clock, if present, is automatically loaded into the date
and time so this is used as the initial value for editing. If more than one real time clock (RTC) is present the date and time from the keypad is used, if
not then the date and time from the lowest number slot with a real time clock is used.
The Date and Time used for time stamping trips will continue to use the originally selected clock even if the Date, Time Selector is changed until a
drive reset is initiated. If Date, Time Selector has been changed and a reset is initiated the trip dates and times are reset to zero.
Powered up time (ms)
When a trip occurs the time in milliseconds since the drive was powered up is also stored in
Trip Time Identifier (L72) since powered up. The time will
roll over when it reaches 2
31
- 1, if the time is 0 a value of 1 is written.

If a keypad installed to the front of the drive includes a real time clock (RTC) then the date, time from this clock is displayed,
otherwise the date, time is set to zero
