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 HD3Z
•
Fan fault
•
Fault occurs to temperature
detection circuit
•
Use inverter with higher power capacity
•
Improve the ventilation around HD3Z
•
Replace the cooling fan
•
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
E0013
Soft start contactor
failed
•
Contactor fault
•
Control circuit fault
•
Replace the contactor
•
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 HD3Z, 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 HD3Z is severely
unbalanced
•
Check the connection between HD3Z
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
•
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)
•
Select F02.00 = 2
•
Check mains supply voltage
•
Use HD3Z with proper power rating
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
E0020 Motor overheat
•
Motor overheat
•
The setting of motor parameter is
incorrect
•
Reduce the load; Repair or replace the
motor
•
Increase Acc. / Dec. time (F03.01 -
F03.08)
•
Set correct motor parameter (F08.00 -
F08.04)
