Contains the last 10 drive trips. (Pr 10.20 = {tr01, 0.51}) is the most recent trip and (Pr 10.29 = {tr10, 0.60}) the oldest. When a new trip occurs all the
parameters move down one, the current trip is put in (Pr 10.20 = {tr01, 0.51}) and the oldest trip is lost from the bottom of the log. Descriptions of the
trips are given in Table 5-8 below. All trips are stored, including HF trips numbered from 20 to 29. (HF trips with numbers from 1 to 16 are not stored in
the trip log.) Any trip can be initiated by the actions described, or 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.

Check for short circuit on armature cabling
Check integrity of motor insulation
Check current loop stability
AOP Voltage has been applied to the armature but no current feedback has been detected
158
Check the armature circuit
AtL.Err Power processor armature timing loop cannot operate with the current PLL synchronisation and the firing angle demand
161
This can occur if the PLL is in the process of losing synchronization but has not yet asserted a PLL Err (trip 174).
C.Acc SMARTCARD trip: SMARTCARD Read / Write fail
185
Check SMARTCARD is installed / located correctly
Ensure SMARTCARD is not writing data to data location 500 to 999
Replace SMARTCARD
C.boot
SMARTCARD trip: The menu 0 parameter modification cannot be saved to the SMARTCARD because the necessary file
has not been created on the SMARTCARD
177
A write to a menu 0 parameter has been initiated via the keypad with Pr 11.42 (SE09, 0.30) set to auto(3) or boot(4), but the
necessary file on the SMARTCARD has not been created.
Ensure that Pr 11.42 (SE09, 0.30) is correctly set and reset the drive to create the necessary file on the SMARTCARD
Re-attempt the parameter write to the menu 0 parameter
C.bUSY SMARTCARD trip: SMARTCARD can not perform the required function as it is being accessed by a Solutions Module
178 Wait for the Solutions Module to finish accessing the SMARTCARD and then re-attempt the required function
