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
