HD30 Series Inverters User Manual ―125―
Fault code Fault name Possible reasons of fault Counter-measures
E0017 Inverter overload
• Acceleration time is too short
• Improper setting of V/f curve or
torque boost leads to over
current
• Instant power-off occurs, the
running motor is restarted
• Mains supply voltage is too low
• Motor load is too high
• Adjust acceleration time (F03.01、
F03.03、F03.05、F03.07)
• Adjust V/f curve (F09.00—
F09.06) or torque boost (F09.07,
F09.08)
• Please set start mode to be
speed tracking (F02.00=2)
• Please check mains supply
voltage
• Please use inverter with proper
power rating
E0018
Inverter output is
unloaded
• Load disappeared or comes
down suddenly
• Parameters are not set properly
• Please check load and
mechanical transmission devices
• Please set the parmeters
properly (F20.03—F20.05)
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’s overload protection
factor is not set properly
• Motor runs with blocked torque
or load is too heavy
• Adjust the setting of V/f curve
(F09.00—F09.06)
• Check the power input
• Please use special motor if the
motor needs to operate for a long
time with heavy load
• Please properly set the overload
protection factor of the motor
• Please check the load and
mechanical transmission devices
E0020 Motor overheat
• Motor overheat
• The setting of motor
paramteters is incorrect
• Reduce the load; Repaire or
replace the motor; Increase the
acceleration/deceleration time
(F03.01—F03.08)
• Set the motor parameter (F08.00
－F08.04、F13.01－F13.05)
E0021
Access fault of
Control board
EEPROM
• Memory circuit fault of control
board EEPROM
• Please contact the supplier for
repairing
E0022
Access fault of
display panel
EEPROM
• Memory circuit fault of display
panel EEPROM
• Replace the display panel
• Please contact the supplier for
repairing
E0023
Fault 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
• Please set correct value of motor
parameters (F08.00－F08.04、
F13.01－F13.05)
E0024
Fault of external
equipment
• Fault terminal of external
equipment operates
• Please check external equipment
Mark: E0022 doesn’t affect the inverter normal operation.
