E0017 Inverter overload
E0018 Inverter output is
unloaded
E0019 Motor Overload
E0020 Reserved
E0021 Access fault of Control
Board EEPROM
ï Output phase disconnection or loss
Heavy imbalance of inverter's three-
ï
phase load
ï Acceleration time is too short
ï Improper setting of V/f curve or
torque boost leads to over
current
ï Instant power-off occurs, the running
motor is restarted
ï Mains supply voltage is too low
ï Motor load is too high
ï Load disappeared or comes
down suddenly
ï Parameters are not set properly
ï Improper setting of V/f curve
ï Mains supply voltage is too low
ï Normal motor runs for a long time
with heavy load at low speed
ï Motor runs with blocked torque
or load is too heavy
ï Memory circuit fault of control board
EEPROM
ï Please check the
connection
between inverter
and motor
ï Please check the quality
of motor
ï Adjust acceleration time
(F03..01,F03.03, F03.05,
F03.07)
Adjust V/f curve (F09.00 –
ï
F09.06) or torque boost
(F09.07,F09.08)
ï Please set start mode to
be speed tracking
(F02.00=2)
ï Please check mains
supply voltage
ï Please use inverter with
proper power rating
ï Please check load and
mechanical transmission
devices
ï Please set the parameters
properly (F20.03-F20.05)
ï Adjust the setting of V/f
curve (F09.00-F09.06)
ï Check the power input
ï Please use special
motor if the motor needs
to operate for a long time
with heavy load
ï Please check the load and
mechanical transmission
devices
ï Please contact the
supplier for repairing
