Fault Fault reasons Counter-measures
E0008
Power module fault
• Short circuit between phases
output
• Short circuit to the ground
• Output current is too high
• Power module is damaged
• Check the connection and connect the
wire properly
• Check the connection and connect the
wire properly
• Check the connection and mechanism
Contact the supplier for repairing
E0009
Heatsink overheat
• Ambient temperature is too high
• Poor external ventilation of HD3N
• Fan fault
• Fault occurs to temperature
detection circuit
• Use inverter with higher power
capacity
• Improve the ventilation around HD3N
• Replace the cooling fan
• Seek technical support
E0010
Braking unit fault
Circuit fault of braking unit
Seek technical support
E0012
Parameters auto-
tuning fault
• Parameter auto-tuning is timeout
• Check the motor connection
• Input correct motor parameters
(F08.00 - F08.04)
• Seek technical support
E0014
Current detection
circuit fault
• Current detection circuit is
damaged
• Contact the supplier for repairing
E0015
Input voltage phase
loss
• For three-phase input HD5L, input
phase loss fault occurs to power
input
• Check the three-phase power input
• Seek technical support
E0016
Output voltage
phase loss
• Output voltage phase
disconnection or loss
• Three-phase load of HD3N is
severely unbalanced
• Check the connection between HD5L
and motor
• Check the quality of motor
E0017
Inverter overload
• Acc time is too short
• Improper setting of motor
parameter
• Improper setting of V/f curve or
torque boost leads to over current
• Did not auto-tune motor in vector
control mode
• Restart motor that is rotating after
sudden instantaneous voltage loss
• Mains supply voltage is too low
• Motor load is too high
• Adjust Acc time (F03.01, F03.03,
F03.05, F03.07)
• Set proper motor parameter (F08.00 -
F08.04)
• Adjust V/f curve (F09.00 - F09.06) or
torque boost (F09.07,F09.08)
• Do parameter auto tuning (F08.06)
• Set F02.00 = 2
• Check mains supply voltage
• Use HD3Nr with proper power rating
E0018
Inverter output load-
loss
• Load disappears or falls suddenly
• Parameters are not set properly
• Check load and mechanical
transmission devices
• Set the parmeters properly (F20.03 -
F20.05)
E0019
Motor overload
• Improper setting of V/f curve
• Mains supply voltage is too low
• Normal motor runs for a long time
with heavy load at low speed
• Motor locked-rotor or overload
• Adjust V/f curve (F09.00 - F09.06)
• Check the power input
• Use special motor if the motor needs
to operate for a long time with heavy
load
• Check the load and mechanical
transmission devices
