overvoltage
3.the deceleration time is
too short
4.didn't install braking
unit and braking resistor
1.there is external force
to drag the motor to run
when running
2.the input voltage is
high
The range of input
voltage is not within the
failure
specification
1.the momentary power
cut
2.the inverter's input
voltage is not within the
specification
3.the bus voltage is not
normal
fault
4.the rectifier bridge and
buffer resistance are
abnormal
5.the drive panel is
abnormal.
6.the control panel is
abnormal
1.the type selection of
inverter is small
2.whether the load is too
large or the motor stall

normal range
3.cancel the external
force or install braking
resistor.
4.increase acceleration
time
1.set the voltage to the
normal range
2.cancel the external
force or install braking
resistor.
3.increase the
deceleration time
4.install braking unit and
brake resistor
1.cancel the external
force or install braking
resistor.
2.set the voltage to the
normal range
Adjust the voltage to the
range of the
requirements of
specification
1.reset fault
2.adjust the voltage to
the normal range
3.seek for technical
support
1.choose the inverter
with large power level
2.reduce the load and
check the motor and its
