Fault ID
Failure type
Possible causes
Solutions
4
Err.04
Constant speed
overcurrent
1.the short-circuit or earthing of
inverter output happens
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
1.eliminate peripheral faults
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
5
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
The range of input voltage is not
within the specification
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
