Fault type
Possible cause of
failure
Countermeasures
running overcurrent too short.
The
V/F
curve
is
improper.
Adjust the V/F curve setting, adjust the
manual torque boost or set the motor
parameters correctly to ensure that the
automatic torque boost is normal.
When an instant stop
occurs, restart the motor
in rotation.
Set the start mode F2.00 to speed
tracking restart function.
Low power grid voltage Check the input power.
The drive power is too
small.
Use a drive with a large power level.
E002
Drive
decelerated
running overcurrent
The deceleration time is
too short.
Extend the deceleration time.
Load
with
potential
energy or large inertia
torque
Externally add a proper energy
consumption braking component.
The drive power is small. Use a drive with a large power level.
E003
Drive
constant-speed
running overcurrent
Sudden change of load
Reduce the sudden change of load.
The
acceleration/deceleration
time is set to short.
Extend the acceleration/deceleration
time as appropriate.
Abnormal load
Perform load check.
Low power grid voltage Check the input power.
The drive power is small. Use a drive with a large power level.
E004
Drive
accelerated
running overvoltage
Abnormal input voltage Check the input power.
The acceleration time is
set to short.
Extend the acceleration time as
appropriate.
When an instant stop
occurs, restart the motor
in rotation.
Set the start mode F2.00 to speed
tracking restart function.
E005
Drive
decelerated
running overvoltage
The deceleration time is
too short (relative to
regenerative energy).
Extend the deceleration time.
Load
with
potential
energy or large inertia
torque
Select a proper energy consumption
braking component.
E006
Drive
constant-speed
running overvoltage
Abnormal input voltage Check the input power.
The
acceleration/deceleration
time is set to short.
Extend the acceleration/deceleration
time as appropriate.
Abnormal change of the
input voltage
Install an input reactor.
