Fault
Type
E007
Over current
When
Acceleration
(OVI)
•
Check the power supply
•
Avoid restarting the motor until it stops
completely
1. High input voltage
2. Regenerative energy
from the motor is too large
E008
Over current
during
Deceleration
(OV2)
•
Increase Dec. time
•
Reduce load or use higher power
controller
•
Check the power supply
1. Dec time is too short
2. Load is too big
3. High input voltage
E009
Over
voltage
When
running at
Constant
Speed
(OV3)
•
Install input reactor
•
Increase braking
1. High input voltage
2. Load is too big
E010
•
Check the power supply
1. Low input voltage
DC Bus
Under
Voltage
(UV)
E011
•
Check the power supply
•
Set the rated current of motor properly
•
Check the load, adjust the value of
torque boost
•
Select proper power motor
1. Low input voltage
2. Wrong setting of motor
parameter
3. Motor locked rotor or
sudden big change of load
to small load
4. The power of motor is
too small
Motor
Overload
(OL1)
E012
•
Prolong Acc time
•
Avoid restarting the motor until it stops
completely
•
Check the power supply
•
Select bigger capacity controller
1. Acc time is too short
2. Restart the motor when it
is decelerating
3. Low input voltage
4. Load is too big
Controller
Overload
(OL2)
E013
•
Check the wiring, installation and the
power supply
1. Loss of phase occurred
in power supply
Input Phase
Failure
(SP1)
E014
•
Check the output wiring, cable and
motor
1. Loss of phase occurred
in output side of main
Output
Phase
Failure
(SP0)
