1.7 FAULT DISPLAY AND TROUBLESHOOTING

If a fault occurs and the inverter functions are lost, check for the causes and provide proper corrective
actions, referring to the following checking method.
Contact your TECO representative if any fault other than described below occurs, if the inverter itself
malfunctions, if any parts are damaged, or if you have any other problems.

1.7.1 Checking of Causes

The inverter has protective functions to protect it from faults such as overcurrent or overvoltage. If a fault
occurs, the protective functions operate to shut off the inverter output and the motor coasts to a stop. At the
same time, the fault contact signal is output.
When the protective functions operate in models with analog operator, LED displays a fault show in
table 1.6. Also when the digital operator is used, the fault display is provided as shown in table 1.8.
The operation can be restarted by turning ON the fault reset input signal (or RESET key of the digital
operator) or turning OFF the power supply and ON again.
