3.The voltage is low
4.whether suddenly increase the
load when running
5.The type selection of inverter is
small
range
4.Cancel the sudden load
5.Choose the inverter with
large power level

Err.05
Acceleration
over voltage
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
over voltage
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
Over voltage
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. Frequent under voltage failures
Adjust the voltage to the range
of the requirements of
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
12
Err.12
Input phase loss
1.The drive panel is abnormal.
2.The lightning protection plate is
abnormal
3.The main control panel is
abnormal
4.The three-phase input power is
not normal
1.Replace the drive, the power
board or contactor
2.Seek for technical support
3.Check and eliminate the
existing problems in the
peripheral line
13
Err.13
Output phase
loss
1.The lead wires from the inverter
to the motor is not normal
1.Eliminate peripheral faults
2.Check the motor's three-
