HD3N-TC Series Inverter User Manual V1.0 ―69―
Fault Fault reasons Counter-measures
E0019
Motor overload
• Improper setting of V/f curve
• Mains supply voltage is too low
• Normal motor runs for a long time
with heavy load at low speed
• Motor locked-rotor or overload
• Adjust V/f curve (F09.00 - F09.06)
• Check the power input
• Use special motor if the motor needs
to operate for a long time with heavy
load
• Check the load and mechanical
transmission devices
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
E0023
Faulty setting of
parameters
• The power rating between motor and
inverter is too different
• Improper setting of motor
parameters
• Select an inverter with suitable power
rating
• Set correct value of motor parameters
(F08.00 - F08.04)
E0024
Fault of external
equipment
• Fault terminal of external equipment
operates
• Check external equipment
E0028
SCI communication
timeout
• Connection fault of Communication
cable
• Disconnected or not well connected
• Check the connection
E0029
SCI communication
error
• Connection fault of communication
cable
• Disconnected or not well connected
• Communication setting error
• Communication data error
• Check the connection
• Check the connection
• Correctly set the communication
format (F17.00) and the baud rate
(F17.01)
• Send the data according to MODBUS
protocol
E0030
Brake fault
• Brake contactor does not act
• Brake contactor is damaged
• Brake contactor is nornally run, but
there is no feedback signal
• Check wiring of brake
• Replace brake contactor
• Check feedback wiring
E0032
Brake releasing is
abnormal
• Detection time for brake releasing
abnormal is too short
• Brake releasing current/torque is too
high
• Properly set detection time for brake
releasing
• Adjust brake releasing current/torque
Note:
E0022 does not affect the normal use of inverter.
