to see if any problem occurs
a. Replace either the entire drive
or the control board if the
problem continues to occur.

Input Phase Loss
Drive input power
has a large
imbalance of voltage
between phases or
has an open phase
(Detected when P7-
00=1)
1. Phase loss in the drive
input power
2. Drive input power
terminals has a loose wiring
3. Drive input power voltage
has an excessive fluctuation
4. The main circuit capacitors
are impaired
1. Check wiring for errors in the
main circuit drive input power
»Correct wiring
2. Make sure the terminals are
tightened correctly
»Apply the tightening torque as
showed in the manual
3. Confirm the voltage from the
drive input power
»Apply possible solutions for
drive 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.
LF1
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
