Chapter 5 Fault Countermeasures and
Abnormality Handling
5.1 Fault Phenomena and Countermeasures
When the drive is abnormal, LED digit tube will display corresponding fault
codes and its contents, the drive will stop outputting, when a fault occurs, if the
motor is rotating, it will park freely, till it stops rotating. Fault types of the drive
which may occur are shown in Table 5-1, when the drive is fault, users should
carry out examination according to this table first, and record fault phenomena in
details, when technical services are required, please contact the After sale Dept. of
our company directly, or contact dealers of the company.
