high
3.there is external force
to drag the motor to run
when accelerating.
4.the acceleration time is
too short
normal range
3.cancel the external
force or install braking
resistor.
4.increase acceleration
time

Err.06
Deceleration
overvoltage
1.the input voltage is
high
2.there is external force
to drag the motor to run
when decelerating.
3.the deceleration time is
too short
4.didn't install braking
unit and braking resistor
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

Err.07
Constant
speed
overvoltage
1.there is external force
to drag the motor to run
when running
2.the input voltage is
high
1.cancel the external
force or install braking
resistor.
2.set the voltage to the
normal range

Err.08
Control power
failure
The range of input
voltage is not within the
specification
Adjust the voltage to the
range of the
requirements of
specification

Err.09
Under voltage
fault
1.the momentary power
cut
2.the inverter's input
voltage is not within the
specification
3.the bus voltage is not
normal
4.the rectifier bridge and
buffer resistance are
abnormal
5.the drive panel is
abnormal.
6.the control panel is
abnormal
1.reset fault
2.adjust the voltage to
the normal range
3.seek for technical
support

Err.10
Inverter overload
1.the type selection of
inverter is small
2.whether the load is too
large or the motor stall
1.choose the inverter
with large power level
2.reduce the load and
check the motor and its
