The bits in this parameter correspond to the status bits in menu 10 as follows.
When Pr 6.49 = 0
The trip time log Pr 10.42 to Pr 10.51 is disabled and these parameters will always remain zero.
When Pr 6.49 = 1
When a trip occurs the reason for the trip is put into the top location in the trip log (Pr 10.20). At the same time either the time from the powered-up
clock (if Pr 6.28 = 0) or from the run time clock (if Pr 6.28 = 1) is put into Trip 0 time (Pr 10.41 and Pr 10.42). The times for earlier trips (Trip 1 to 9) are
moved to the next parameter in the same way that trips move down the trip log. The time for Trips 1 to 9 are stored as the time difference between
when Trip 0 occurred and the relevant trip in hours and minutes. The maximum time difference that can be stored is 600 hours. If this time is
exceeded the value stored is 600.00.
If the powered-up clock is used as the source for this function all the times in the log are reset to zero at power-up because they were related to the
time since the drive was powered-up last time. If the runtime clock is used the times are saved at power-down and then retained when the drive
powers up again. If Pr 6.28, which defines the clock source, is changed by the user the whole trip and trip time logs are cleared. It should be noted
that the powered-up time can be modified by the user at any time. If this is done the values in the trip time log remain unchanged until a trip occurs.
The new values put in the log for earlier trips (Trip 1 to 9) will become the time difference between the value of the power-up clock when the trip
occurred and the value of the powered-up clock when the latest trip occurred. It is possible that this time difference may be negative, in which case
the value will be zero
