Fault Fault Reasons Counter-measures
E09
Heatsink overheat
• Ambient temperature is too high
• Poor external ventilation of HD5L-
PLUS
• Fan fault
• Fault occurs to temperature
detection circuit
• Use controller with higher power
capacity
• Improve the ventilation around
HD5L-PLUS
• Replace the cooling fan
•
Seek technical support
E10
Braking unit fault
• Circuit fault of braking unit • Seek technical support
E11
CPU fault
• CPU abnormal
• Detect at power up after completely
power down
•
Seek technical support
E12
Motor auto-tuning
fault
• Parameter auto-tuning is time out
• Check the motor connection
• Input correct nameplate parameters
• Seek technical support
E13
The power-on buffer
contactor is not
closed
• Contactor fault
• Control circuit fault
• Replace the contactor
• Seek technical support
E14
Current detection
fault
• Current detection circuit is
damaged
• Contact the supplier for repairing
E15
Input voltage phase
loss
• For three phase input HD5L-PLUS,
input phase loss fault occurs to
power input
• Check the three phase power input
• Seek technical support
E16
Output voltage phase
loss
• Output voltage phase
disconnection or loss
• Three phase load of HD5L-PLUS is
severely unbalanced
• Check the connection between
HD5L-PLUS and motor
• Check the quality of motor
E17
Controller overload
• Acc. time is too short
• Improper setting of V/f curve or
torque boost leads to over current
• Mains supply voltage is too low
•
Motor load is too high
• Adjust Acc. time
• Adjust V/f curve or torque boost
• Check mains supply voltage
• Use controller with proper power
rating
E18
Excessive speed
deviation
• Brake fault or contactor fault
• PG pulse number fault
• Improper setting of F05.19, F05.20
• Inadequate controller torque
• Speed-loop PI parameter setting is
incorrect
• Change contactor
• Set proper PG P/R
• Correct the setting of F05.19 - F05.20
• Select bigger capacity
• Correctly set speed-loop PI
parameter
E19
Motor overload
• Improper setting of V/f curve
• Mains supply voltage is too low
• Overload protection factor of
motor is not set properly
• Motor blocked-rotor torque or
overload
• Adjust V/f curve
• Check the power input
• Properly set the overload protection
factor of the motor
• Check the load and mechanical
transmission devices
