Possible causes
Solutions
4.the voltage is low
5.suddenly increase the load in
the process of deceleration.
6.didn't install braking unit and
braking resistor
6.install braking unit and brake
resistor

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

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

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 occurs
1.choose the inverter with large
power level
2.reduce the load and check the
motor and its mechanical
conditions

Err.11
Motor
Overload
1. power grid voltage is too
low
1.check the power grid voltage
