Fault Name Cause Possible Solution
input power stabilization
4. Check drive input power. If drive
input power seems normal but the
alarm continues to occur, replace
either the entire drive or the
control board. Contact the local
distributor for more information.

Output Phase Loss
Phase loss on the
drive output side
1. The output cable is not
connected
2. The motor winding is
impaired
3. The output terminal is loose
4. The rated current of the
motor being used is 5% less
than the drive rated current
5. An output transistor is
impaired
6. A single phase motor is
activating
1.Check the errors for wiring then
properly connect the output cable
»Correct the wiring
2.Check the resistance which
located between motor lines
»If the winding is impaired, replace
the motor
3.Use tightening torque which
showed in the manual in order to
fasten the terminal
4.Check motor capacities and the
drive
5.The drive cannot run a single
phase motor

Speed Deviation (for
closed-loop control
method)
The deviation
between the speed
feedback and speed
reference is longer
than the time set to
F1-13 and greater than
the setting in F1-12
1. The load is too heavy
2. The deceleration and
acceleration times are too
short
3. The load is locked up
4. Inappropriate parameter
settings
5. Motor is being braked by a
mechanical brake
1. Reduce the load
2. Increase the deceleration and
acceleration times C1-00 to C1-07
3. Check the machinery
4. Check the F1-12 (Speed
Deviation Detection Level) and
F1-13 (Speed Deviation Detection
Delay Time) settings
5. Check the motor brake and
make sure it is released
