High Feedback Sensed
The feedback level is more than the level set in
Y1-11
[High Feedback Level]
for the time set in
Y1-12
[High Feedback Lvl Fault Dly Time]
.
•
Decrease the feedback level less than
Y1-11
.
•
Set
Y1-11
and
Y1-12
correctly.
Note:
•
Do a Fault Reset to clear the fault.
•
If the drive detects this fault, it will respond as specified by the setting of
Y1-13 [High Feedback Selection]
.
•
Parameter
L5-41 [Hi Feedback Flt Retry Selection]
sets the Auto Restart function of this fault.

YF-12 [PI Aux Control High Level Detect]
for the
time set in
YF-13 [PI Aux High Level Detection Time]
in these conditions:
•
The drive operates in AUTO Mode.
•
The output frequency > 0.
•
Decrease the PI Auxiliary Feedback level less than
YF-12
.
•
Set
YF-12
and
YF-13
correctly.
Note:
•
Do a Fault Reset to clear the fault.
•
Parameter

HLCE
High Level Communication Errors
Communication data error occurred between the
option and the master drive when you use Gateway
function.
The master drive detects
oFxxx
and the slave drive
detects
HLCE
.
Examine the wiring between the option and the master drive and
remove the cause of the fault.
Note:
This fault occurs when the drive is a slave drive in Gateway Mode
[F6-16 ≠ 0]
and communication is lost from the master.

LF
Output Phase Loss
The motor main circuit cable is disconnected.
Connect motor main circuit cable wiring. Correct wiring errors in
the main circuit drive input power.
There is a disconnection in the motor coil winding.
If a coil is disconnected, measure the motor Line-to-Line Resistance
and replace the motor.
The screws on the drive output terminals are loose.
Tighten the terminal screws to the correct tightening torque.
The rated output current of the motor is less than 5%
of the drive rated current.
Examine the drive capacity or the motor output to be applied.
You are trying to use a single-phase motor.
The drive cannot operate a single-phase motor.
The output transistor in the drive is damaged.
•
Re-energize the drive.
•
If the fault stays, replace the control board or the drive. For
information about replacing the control board, contact Yaskawa
or your nearest sales representative.
Note:
•
The drive detects this fault if phase loss occurs on the output side of the drive.
•
Do a Fault Reset to clear the fault.
•
Set
L8-07 [Output Phase Loss Protection Sel]
to enable and disable
LF
detection.

LF2
Output Current Imbalance
Phase loss occurred in the wiring on the output side
of the drive.
Examine for wiring errors or disconnected wires on the output side
of the drive, and repair problems.
The output terminal screws of the drive are loose.
Tighten the terminal screws to the correct tightening torque.
The drive output circuit is broken.
•
Re-energize the drive.
•
If the fault stays, replace the control board or the drive. For
information about replacing the control board, contact Yaskawa
or your nearest sales representative.

Low Feedback Sensed
The feedback level is less than the level set in
Y1-08
[Low Feedback Level]
for the time set in
Y1-09 [Low
Feedback Lvl Fault Dly Time]
.
•
Increase the feedback level to more than
Y1-08
.
•
Set
Y1-08
and
Y1-09
correctly.
Note:
•
Do a Fault Reset to clear the fault.
•
If the drive detects this fault, it will respond as specified by the setting of
Y1-10 [Low Feedback Selection]
.
•
Parameter
L5-40 [Low Feedback Flt Retry Selection]
sets the Auto Restart function of this fault.
