7.1 Fault Causes and Troubleshooting
Once drive fault occurs, please identify the causes of fault carefully and make a detailed record
of fault symptom. To seek services, please contact the dealer.
Parameters U1-00, U1-09 and U1-18 are used to view the fault history of fault 1 (fault 1 =
the most recent fault), fault 2 (fault 2 = the second most recent fault), and fault 3 (fault 3 = the
third most recent fault). Faults are recorded with numeric codes (0~46), while the fault
information that corresponds to each numeric fault code is specified in the table below.
 ATTENTION:
When a fault occurs, please identify the causes and seek solutions according the guidance
in the table. If the fault fails to be solved, do not apply power to the drive again. Contact the
supplier for service in time
