13.2 Trip indications
The output of the drive is disabled under any trip condition so that the
drive stops controlling the motor. If the motor is running when the trip
occurs it will coast to a stop.
During a trip condition, where a KI-Keypad is being used, the upper row
of the display indicates that a trip has occurred and the lower row of the
keypad display will display the trip string. Some trips have a sub-trip
number to provide additional information about the trip. If a trip has a
sub-trip number, the sub-trip number is flashed alternately with the trip
string unless there is space on the second row for both the trip string and
the sub-trip number in which case both the trip string and sub-trip
information is displayed separated by a decimal place.
The back-light of the KI-Keypad display will also flash during a trip
condition. If a display is not being used, the drive LED Status indicator will
flash with 0.5 s duty cycle if the drive has tripped. Refer to Figure 13-2.
Trips are listed alphabetically in Table 13-3 based on the trip indication
shown on the drive display. Alternatively, the drive status can be read in
Pr 10.001 'Drive OK' using communication protocols. The most recent
trip can be read in Pr 10.020 providing a trip number. It must be noted
that the hardware trips (HF01 to HF20) do not have trip numbers. The
trip number must be checked in Table 13-4 to identify the specific trip.
Example
1. Trip code 2 is read from Pr 10.020 via serial communications.
2. Checking Table 13-3 shows Trip 2 is an Over Volts trip.
Comms
3. Look up Over Volts in Table 13-3.
4. Perform checks detailed under Diagnosis.
