Chapter 8 Troubleshooting and Maintenance
8.1 Troubleshooting
If a fault occurs, the keypad will display the fault alarm status. Meanwhile, faulty relay acts, accordingly
HD3L 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 the
Table 8-1. If technical help is needed, contact the suppliers or directly call Shenzhen Hpmont
Technology Co., Ltd.
After the fault is eliminated, reset HD3L by any of the following methods:
1. Keypad reset.
2. External reset terminal (multi-function terminal = No. 16 function).
3. Communication fault reset.
4. Switch on HD3L after completely power off.
Table 8-1 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 powering on and
powering off
• Check input power voltage
• Check wiring and wire HD3L properly
E0001 Acc overcurrent
• Improper connection between
controller and motor
• Improper motor parameters
• The rating of the used HD3L is too
small
• Acc / Dec time is too short
• Connect HD3L and motor properly
• Set correct motor parameters
• Select controller with higher rating
• Set proper Acc time and Dec time
E0002 Dec overcurrent
E0003
Constant speed
overcurrent
E0004 Acc over voltage
• Input voltage is too high
• Deceleartion time is too short
• Improper wiring leads to
overvoltage of hardware
• Check power input
• Set a proper value for Dec time
• Check wiring and wire HD3L properly
E0005 Dec over voltage
E0006
Constant speed over
voltage
E0008 Power module fault
• Short circuit between phases
output or the ground
• Output current is too high
• Power module is damaged
• 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 HD3L
• Fan fault
• Fault occurs to temperature
detection circuit
• Use controller with higher power
capacity
• Improve the ventilation around HD3L
• Replace the cooling fan
• Seek technical support
E0010 Braking unit fault
• Circuit fault of braking unit • Seek technical support
