type
Failure type
Possible causes
Solutions
2.The control mode is vector and
without identification of
parameters
3.The voltage is low
4. Whether suddenly increase the
load when running
5.The type selection of inverter is
small
2.Perform identification
for the motor parameters
3.Set the voltage to the
normal range
4.Cancel the sudden load
5.Choose the inverter with
large power level

Err.05
Acceleration
overvoltage
1.Didn't install braking unit and
braking resistor
2.The input voltage is high
3.There is external force to drag the
motor to run when accelerating.
4.The acceleration time is too short
1.Install braking unit and
brake resistor
2.Set the voltage to the
normal range
3.Cancel the external force
or install braking resistor.
4.Increase acceleration
time
6
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
7
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
8
Err.08
Control power
failure
1.The range of input voltage is not
within the specification.
2.Report undervoltage fault
frequently.
Adjust the voltage to the
range of within the
specification
9
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
10
Err.10
Inverter
overload
1.The type selection of inverter is
small
2.Whether the load is too large or
the motor stall occurs
1.Choose the inverter with
large power level
2.Reduce the load and
check the motor and its
mechanical conditions
11
Err.11
Motor
Overload
1.Power grid voltage is too low
2.Whether the setting motor
protection parameters (F8.03) is
appropriate or not
3.Whether the load is too large or
the motor stall occurs
1.Check the power grid
voltage
2.Correctly set this
parameter.
3.Reduce the load and
check the motor and its
mechanical conditions
