Fault name Possible reasons of fault Counter-measures
speed process)
E0007 Stall overvoltage
• Bus voltage is too high
• The setting of stall
overvoltage is too low.
• Please check power input or
the function of brake
• Set the value of stall
overvoltage properly
E0008
Fault of power
module
• Short circuit between phases
output
• Short circuit to the ground
• Output current is too high
• Power module is damaged
• Please check the connection
and connect the wire properly
• Please check the connection
and connect the wire properly
• Please check the connection
and mechanism
• Please contact the supplier for
repairing
E0009
Heatsink
overheat
• Ambient temperature is too
high
• Inverter external ventilation is
not good
• Fan fault
• Fault occurs to temperature
detection circuit
• Please use inverter with higher
power capacity
• Improve the ventilation around
the inverter
• Replace the cooling fan
• Please seek technical support
E0010
Fault of braking
unit
• Circuit fault of braking unit • Please seek technical support
E0011 CPU fault • CPU abnormal
• Please detect at power on after
completely power outage
• Please seek technical support
E0012
Parameters
auto-tuning fault
• Parameter auto-tuning is time
out
• Please check the motor’s
connection
• Input the correct nameplates
parameters
• Please seek technical support
E0013
Contactor is not
actuated
• Contactor fault
• Fault of control circuit
• Replace the contactor
• Please seek technical support
E0014
Fault of current
detection circuit
• Current detection circuit is
damaged
• Please contact the supplier for
repairing
E0015
Fault of input
phase
• For three-phase input
inverter, input phase loss fault
occurs to power input
• Please check the three-phase
power input
• Please seek technical support
E0016
Fault of output
phase
• Output phase disconnection
or loss
• Heavy imbalance of inverter’s
three-phase load
• Please check the connection
between inverter and motor
• Please check the quality of
motor
E0017 Inverter overload
• Acceleration time is too
short
• Improper setting of V/f curve
or torque boost leads to over
current
• Instant power-off occurs, the
running motor is restarted
• Adjust acceleration time
• Adjust V/f curve or torque
boost
• Please set start mode to be
speed tracking
• Please check mains supply
voltage
