9.13 Trips and sub-trip numbers
The drive retains a log of the last ten trips that have occurred. Trip 0 to Trip 9 store the 10 most recent trips that have occurred where Trip 0 is the
most recent and Trip 9 is the oldest.
When a new trip occurs it is written to Trip 0, all the other trips move down the log, with the oldest being lost.
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. If the trip does not have a sub-trip number then zero is stored in the sub trip log.
If any parameter between Trip 0 (L29) through to Trip 9 (L38) inclusive is read by communication protocols, the trip numbers in
Table 9-15 Serial communications look up table on page 473 are read for the relevant drive trip.
9.14 Travel interrupt code
To assist in diagnosing a fault during operation, the sequence of the travel is continuously monitored within the Elevator control software. During a
fault a travel interrupt code will be generated to indicate the point during operation where the fault occurred. The travel interrupt code is available in
Travel Interrupt Code (L03).
Table 9-12 Travel interrupt codes
Travel Interrupt Code (L03) Description
0 No travel interrupt
1 Travel interrupt while waiting for the enable input
2 Travel interrupt during the motor contactor de-bounce time
3 Travel interrupt during torque ramp-up torque / brake release
4 Travel interrupt during the brake release delay
5 Travel interrupt during the load measurement delay
6 Travel interrupt during start optimization
7 Travel interrupt during acceleration
8 Travel interrupt during normal travel
9 Travel interrupt during deceleration
10 Travel interrupt during creep
11 Travel interrupt during positioning
12 Travel interrupt during brake apply delay
13 Travel interrupt during torque ramp-down / brake apply
