Figure 6-2 Location of the status LED
Any trip can be initiated 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.
Trips can be reset after 1.0s if the cause of the trip has been rectified.
A full list of drive trips can be found in the
Unidrive SP User Guide / Commander GP20
User Guide.
6.1.2 Commander SK
The drive retains a log of the last 10 trips that have occurred in Pr 10.20 to Pr 10.29 .
Pr 10.20 is the most recent trip, or the current trip if the drive is in a trip condition, and
Pr 10.29 is the oldest trip. Each time a new trip occurs, all the parameters move down
one, such that the current trip (and time) is stored in Pr 10.20 and the oldest trip is lost
from the bottom of the log.
If any parameter between Pr
10.20 and Pr 10.29 inclusive is read by serial
communications, then the trip number in section 6.3 Commander SK trip
descriptions on page 35 is the value transmitted.

A full list of drive trips can be found in the
