Chapter 8 Troubleshooting and Maintenance
8.1 Troubleshooting
HD09-S has inbuilt protective and warning self-diagnostic functions. If a fault occurs, the fault code will
be displayed on the display keypad. At the same time, fault relay acts, accordingly the inverter stops
output and the motor coasts to stop.
When fault or alarm occurs, please record the fault details and take proper actions according to the
below table. If you need some technical help, please contact to the suppliers or directly call Shenzhen
Hpmont Technology Co., Ltd..
After the fault is eliminated, please reset the inverter by any of the following methods:
1. Display keypad. Press (standard) / (optional).
2. External reset terminal (DI terminal set as No.46 function).
3. Communication.
4. Switching on the inverter after switching off.
Fault Fault reasons Counter-measures
-Lu-
DC bus undervoltage
• At the begining of powering on
and at the end of powering off
• Input voltage is too low
• Improper wiring leads to
undervoltage of hardware
• It is normal status of powering on and
powering off
• Please check input power voltage
• Please check wiring and wire the
inverter properly
E0001
Inverter output over
current (Acc. process)
• Improper connection between
inverter and motor
• Improper motor parameters
• The rating of the used inverter is
too small
• Acc. / Dec. time is too short
• Vector control, no motor self-
tuning
• Connect the inverter and motor
properly
• Please set correct motor parameters
(F08.00 - F08.04)
• Select inverter with higher rating
• Please set proper Acc. time and Dec.
time (F03.01 - F03.08)
• Perform parameter self-tuning
(F08.06)
E0002
Inverter output over
current (Dec. process)
E0003
Inverter output over
current (constant
speed process)
E0004
DC bus overvoltage
(Acc. process)
• Input voltage is too high
• Deceleartion time is too short
• Improper wiring leads to
overvoltage of hardware
• Improper selection of the braking
devices
• Please check power input
• Please set a proper value for Dec. time
(F03.02, F03.04, F03.06, F03.08)
• Please check wiring and wire the
inverter properly
• Select the brake assembly as
described in section 5.2
E0005
