Table 6-1 listed the possible faults of EV2000. Once a fault occurs, you may check it against the table and record
detailed phenomena before seeking service from your supplier.
Table 6-1 Faults and actions
Fault
code
Fault categories Possible reasons of fault Actions
E001
Over-current
during
acceleration
Too short Acc time Prolong the Acc time
V/F curve is not suitable.
Check and adjust V/F curve, adjust
torque boost or set the motor parameters
correctly to ensure the normal auto
torque boost.
The rotating motor restarts right after stop.
Set F2.00 to “start on fly” function
Low AC supply voltage
Check the drive’s input AC supply
Drive power is too small
Select a high power drive
E002
Over-current
during
deceleration
Too short Dec time
Prolong the Dec time
The load generates energy or the load inertial
is too big
Connect suitable braking kit
Too low drive’s power Select the drive with bigger power
E003
Over-current in
constant speed
operation
Sudden change of load Reduce the change of the load
Too short Acc/Dec time Prolong Acc/Dec time
Abnormal load Check the load
Low AC supply voltage Check the AC supply voltage
Insufficient drive’s power Select the drive with bigger power
E004
Over voltage
during
acceleration
Abnormal AC supply voltage Check the AC supply voltage
Too short Acc/Dec time Prolong the Acc time
The rotating motor re-start after the drive stops
instantly.
Set F2.00 to “start on fly” function
E005
Over voltage
during
deceleration
Too short Dec time (with reference to
generated energy)
Prolong the Dec time
The load generates energy or the load inertial
is too big
Use suitable dynamic braking kit
E006
Over voltage in
constant-speed
operating
process
Abnormal AC supply voltage
Check the AC supply voltage
Too short Acc/Dec time
Prolong the Acc/Dec time
Abnormal change of input voltage
Install input reactor
Too big load inertia Use suitable dynamic braking kit
E007
Drive’s control
power supply
over voltage
Abnormal AC supply voltage
Check the AC supply voltage or seek
service
E008 Input phase loss Any of phase R, S and T cannot be detected
Check the wiring and installation
Check the AC supply voltage
E009
Output phase
failure
Any of Phase U, V and W cannot be detected
Check the drive’s output wiring
Check the cable and the motor
