EF7
External Fault (Terminal DI7)
MFDI terminal DI7 caused an external fault through
an external device.
1.
Find the device that caused the external fault and remove the
caus.
2.
Clear the external fault input in the MFDI.
The wiring is incorrect.
Correctly connect the signal line to MFDI terminal DI7.
External Fault [H1-07 = 2C to 2F]
is set to MFDI
terminal DI7, but the terminal is not in use.
Correctly set the MFDI.
Note:
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 4 [MFDO Function Selection = Alarm]
will activate.

EP24v
External Power 24V Supply
The voltage of the main circuit power supply
decreased, and the 24 V power supply is supplying
power to the drive.
•
Examine the main circuit power supply.
•
Turn ON the main circuit power supply to run the drive.
Note:
•
Set
o2-26 [Ext24V Mode Warning Display]
to enable or disable
EP24v
detection.
•
The drive will not output an alarm signal for this alarm.

FbH
Excessive PID Feedback
The
FbH
detection level is set incorrectly.
Adjust
b5-36 [PID HiHi Limit Level]
and
b5-37 [PID HiHi
Time]
.
There is a problem with the PID feedback wiring.
Correct errors with the PID control wiring.
The feedback sensor is not operating correctly.
Examine the sensors on the control device side.
A fault occurred in the feedback input circuit of the
drive.
Replace the board or the drive. For information about replacing
the control board, contact the manufacturer or your nearest sales
representative.
Note:
•
The drive detects this error if the PID feedback input is more than the level set in
b5-36
for longer than
b5-37
.
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 4 [MFDO Function Select = Alarm]
will activate.
•
If the drive detects this error, it will operate the motor as specified by the stopping method set in
b5-12 [Fdback Loss Select Mode]
.

FbL
PID Feedback Loss
The
FbL
detection level is set incorrectly.
Adjust
b5-13 [Fdback Loss Lvl]
and
b5-14 [Fdback Loss Time]
.
There is a problem with the PID feedback wiring.
Correct errors with the PID control wiring.
The feedback sensor is not operating correctly.
Examine the sensors on the control device side.
A fault occurred in the feedback input circuit of the
drive.
Replace the board or the drive. For information about replacing
the control board, contact the manufacturer or your nearest sales
representative.
Note:
•
The drive detects this error if the PID feedback input is lower than the level set in
b5-13
for longer than
b5-14
.
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 4 [MFDO Function Select = Alarm]
will activate.
•
If the drive detects this error, it will operate the motor as specified by the stopping method set in
b5-12 [Fdback Loss Select Mode]
.

HCA
High Current Alarm
The load is too heavy.
•
Decrease the load for applications with repetitive starts and
stops.
•
Replace the drive with a larger capacity model.
The acceleration time is too short.
•
Calculate the torque necessary during acceleration related to
the load inertia and the specified acceleration time.
•
Increase the values set in
C1-01, C1-03, C1-05, or C1-07
[Acceleration Times]
until you get the necessary torque.
•
Increase the values set in
C2-01 to C2-04 [S-Curve
Characteristics]
until you get the necessary torque.
•
Replace the drive with a larger capacity model.
The drive is trying to operate a specialized motor or
a motor that is larger than the maximum applicable
motor output of the drive.
•
Examine the motor nameplate, the motor, and the drive to
make sure that the drive rated current is larger than the motor
rated current.
•
Replace the drive with a larger capacity model.
The current level temporarily increased because of
speed search after a momentary power loss or while
trying to Auto Restart.
If speed search or Auto Restart cause an increase in current, the
drive can temporarily show this alarm. The time that the drive
shows the alarm is short. No more steps are necessary to clear the
alarm.
Note:
•
The drive detects this error if the drive output current is more than the overcurrent alarm level (150% of the rated current).
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 4 [MFDO Function Selection = Alarm]
will activate.

L24v
Loss of External Power 24V Supply
The voltage of the backup 24 V power supply has
decreased. The main circuit power supply is
operating correctly.
•
Examine the external 24 V power supply for disconnected
wires and wiring errors and repair the problems.
•
Examine the external 24 V power supply for problems.
Note:
•
Set
o2-23 [Ext24V Off Warning Display]
to enable or disable
L24v
detection.
•
The drive will not output an alarm signal for this alarm.
