1 .8 .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 indicating cover, the digital display unit displays a
fault shown in Table 1 .8 . Also when the digital
operator is used, the fault display is provided.
Operation can be restarted by turning ON the
fault reset input signal (or =' key of the digital
E
R ESET
operator) or turning OFF the power supply and ON
again.
