External Fault [H1-06 = 2C to 2F]
is set to MFDI
terminal S6, 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 = 10 [MFDO Function Selection = Alarm]
will activate.

EF7
External Fault (Terminal S7)
MFDI terminal S7 caused an external fault through an
external device.
1.
Find the device that caused the external fault and remove the
cause.
2.
Clear the external fault input in the MFDI.
The wiring is incorrect.
Correctly connect the signal line to MFDI terminal S7.
External Fault [H1-07 = 2C to 2F]
is set to MFDI
terminal S7, 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 = 10 [MFDO Function Selection = Alarm]
will activate.

Emergency Override FWD
The digital input terminal set to
H1-xx = AF [MFDI
Function Selection = Emergency Override FWD]
activated.
When the emergency condition is gone, deactivate the digital input
set to
Emergency Override FWD
.
Note:
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm]
will activate.

Function Selection = Emergency Override REV]
activated.
When the emergency condition is gone, deactivate the digital input
set to
Emergency Override REV
.
Note:
If the drive detects this error, the terminal set to

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 [Ext. Power 24V Supply Display]
to enable or disable
EP24v
detection.
•
The drive will not output an alarm signal for this alarm.

FDBKL
Feedback Loss Wire Break
The analog input from the terminal set to
H3-xx = B
[MFAI Function Selection = PID Feedback ]
is more
than 21 mA or less than 3 mA for longer than 1 s in
these conditions:
•
b5-82 = 1 [Feedback Loss 4
~
20mA Detect Sel =
Alarm Only]
•
b5-01 ≠ 0 [PID Mode Setting ≠ Disabled]
•
H3-01 or H3-09 = 2 [Terminal A1/A2 Signal Level
Selection = 4 to 20 mA]
Make sure that you install the PID feedback source and it operates
correctly.
Note:
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm]
will activate.
•
If the drive detects this error, it will operate the motor as specified by the settings of
b5-82
.
•
Parameter
L5-42 [Feedback Loss Fault Retry Select]
sets the Auto Restart function of this error.

The analog input from the terminal set to
H3-xx = B
[MFAI Function Selection = PID Feedback ]
is more
than 21 mA or less than 3 mA for longer than 1 s in
these conditions:
•
b5-82 = 3 [Feedback Loss 4

Selection = 4 to 20 mA]
Make sure that you install the PID feedback source and it operates
correctly.
Note:
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm]
will activate.
•
If the drive detects this error, it will operate the motor at the speed set in
b5-83 [Feedback Loss Goto Frequency]
as specified by the setting of
b5-82
.

FIRE_ST
Fire Stat Open
The bypass detected a Fire Stat condition.
•
Check the digital input programmed for Fire Stat Switch (Z2-0x
= 38).
•
Check the connected device for continuity.
•
Check Bypass Digital Input Invert Settings in Z2-09 to Z2-16.
