Fault Fault reasons Counter-measures
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 (F19.19)
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
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

• Replace the contactor
• Please seek technical support
E0014
Fault of current
detection circuit
• Current detection circuit is
damaged
• Please contact the supplier for
repairing
E0016
Fault of output phase
• Output phase disconnectionor
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
• Mains supply voltage is too low
• Motor load is too high
• Adjust acceleration time (F03.01)
• Adjust V/f curve (F09.01 - F09.06) or
torque boost (F09.07, F09.08)
• Please check mains supply voltage
• Please use inverter with proper power
rating
