Fault
Code
Fault Type Reason Solution
3: Load inertia is too large 2:Increase deceleration time
3: Add suitable braking units
E009
Under voltage
of DC bus
Input voltage is too low Inspect power grid
E010
Drive
overload
1: Accelerate too fast
2: Restart the motor when
instantaneous trip-off occurs
3: Input voltage is too low
4: Load is too heavy
1:Increase acceleration time
2: Avoid prompt restart when
trip-off
3: Inspect power grid
4: Select larger capacity drive
E011
Motor
overload
1: Input voltage is too low
2: Improper setting of motor
rated current
3: Improper motor’s overload
protection threshold
4: Drive capacity is too low
1: Inspect voltage of power grid
2: Properly setting of motor rated
current
3: Inspect load and boost the
torque
4: Select larger capacity drive
E012
Phase-lack of
input
Phase-lack of R, S, T
Inspect the input power supply or
wiring
E013
Phase-lack of
output
1: There is a broken wire in
the output cable
2: There is a broken wire in the
motor winding.
3.: Output terminals are loose
Check the wiring and installation
E014
Module
overheat
1:Instantaneous over current of
inverter
2:Output short circuit
3: Cooling fans of inverter stop
or damaged. Obstruction of
ventilation channel
4: Ambient temperature is too
high
5: The cables or terminals are
loose
6: Power circuit abnormal
7: Control PCB board abnormal
1: Refer to over current solutions
2: Use the good wire
3: Replace cooling fan and clear
the ventilation channel
4:Decrease the ambient
temperature
5:Inspect and tighten the wire and
terminals
6 and 7: Ask for support
