hpmont HD3N-TC Series - Chapter 6 Troubleshooting

Shenzhen Hpmont Technology Co., Ltd. Chapter 6 Troubleshooting
HD3N-TC Series Inverter User Manual V1.0 ―67―
Chapter 6 Troubleshooting
If a fault occurs, the keypad will display the fault alarm status. Meanwhile, faulty relay acts, accordingly
inverter stops output and the motor coasts to stop.
When fault alarm occurs, user should record the fault in detail and take proper action according to
Table 6-1. If technical help is needed, contact the suppliers or directly call Shenzhen Hpmont
Technology Co., Ltd.
After the fault is eliminated, reset inverter by any of the following methods:
1. Keypad reset.
2. External reset terminal (DI terminal = No. 46 function).
3. Power on inverter again after completely power off.
Table 6-1 Fault and counter-measures
Fault Fault reasons Counter-measures
-Lu-
DC bus
undervoltage
• At the begining of power on and at
the end of power off
• Input voltage is too low
• Improper wiring leads to
undervoltage of hardware
• It is normal status of power on and
power off
• Check input power voltage
• Check wiring and wire inverter
properly
E0001
Inverter output
overcurrent (in 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
• Did not auto-tune motor in vector
control mode
• Connect inverter and motor properly
• Set correct motor parameter (F08.00 -
F08.04)
• Select inverter with higher rating
• Set proper Acc/Dec time (F03.01 -
F03.04)
• Do parameter auto-tuning (F08.06)
E0002
Inverter output
overcurrent (in Dec
process)
E0003
Inverter output
overcurrent (in
constant speed
process)
E0004
DC bus over voltage
(in Acc process)
• Input voltage is too high
• Deceleration time is too short
• Improper wiring leads to overvoltage
of hardware
• Improper selection of the braking
devices
• Check power input
• Set proper Dec time (F03.02, F03.04)
• Check wiring and wire inverter
properly
• Select recommended braking devices
according to section 3.5
E0005
DC bus over voltage
(in Dec process)
E0006
DC bus over voltage
(in constant speed
process)
Note:
E0001 - E0003 can be reset only after reporting for 3s.
