―78― HD3L Series Controller User Manual
Fault Fault reasons Counter-measures
E0011 CPU fault
• CPU abnormal
• Detect at power on after completely
power outage
• Seek technical support
E0012
Parameter
auto-tuning fault
• Parameter auto-tuning is timeout
• Check the motor connection
• Input correct nameplates parameters
• Seek technical support
E0013
Soft start contactor
failed
• Contactor fault
• Control circuit fault
• Replace the contactor
• Seek technical support
E0014
Current detection
fault
• Current detection circuit is
damaged
• Contact the supplier for repairing
E0015
Input voltage phase
loss
• For three-phase input HD3L, Input
voltage 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 HD3L is
severely unbalanced
• Check the connection between HD3L
and motor
• Check the quality of motor
E0017 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
E0018
Excessive speed
deviation
• Brake fault or contactor fault
• PG pulse number fault
• Improper setting 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 HD3L with biger capacity
• Correctly set speed-loop PI parameter
E0019 Motor overload
• Improper setting of V/f curve
• Mains supply voltage is too low
• Overload protection factor of
motor is not set properly
• Motor locked-rotor or overload
• Adjust V/f curve
• Check the power input
• Properly set the overload protection
factor of motor
• Check the load and mechanical
transmission devices
E0020 Motor overheat
• Motor overheat
• Motor overheat terminal (DI or AI
terminal) connects incorrectly
• The setting of motor paramteter is
incorrect
• Reduce the load; Increase the Acc / Dec
time; Repaire or replace the motor
• Detect whether the overheat detection
input signal is correct
• Set the motor parameter according to
the nameplate
E0021
Read / Write fault of
control board
EEPROM
• Memory circuit fault of control
board EEPROM
• Contact the supplier for repairing
E0022
Read / Write fault of
keypad EEPROM
• Memory circuit fault of keypad
EEPROM
• Replace the keypad
• Contact the supplier for repairing
