Minor Faults/Alarms

This section gives information about the causes and possible solutions when a minor fault or alarm occurs. Use the
information in this table to remove the cause of the minor fault or alarm.
Code Name
AFBL Analog Fbk Lost, Switched to Net
Note:
If the drive detects this error, the terminal set to H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm] will activate.
Code Name
AuDis Low PI Aux Fdbk Drive Disabled
Note:
If the drive detects this error, the terminal set to H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm] will activate.
Code Name
AL02 Interlock Open
Code Name
AL03 Emergency Override Bypass
Code Name
AL09 Restart Delay Active
Code Name
AL13 Loss of Load Detected
Code Name
AL16 Input Phase Rotation
Code Name
AL17 Remote Xfer disabled in Reverse
Code Name
AL18 Auto Xfer disabled in Reverse
Code Name
AuFbl PI Aux Fdbk Lost Switched to Net
Note:
• The drive detects this error if it detected a wire-break with the PI Auxiliary Control Feedback [H3-xx = 27] analog signal and it uses PI Auxiliary Feedback.
• If the drive detects this error, the terminal set to H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm] will activate.
Code Name
AUXFB PI Aux Feedback Level Loss
Note:
If the drive detects this error, the terminal set to H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm] will activate.
Code Name
bAT Keypad Battery Low Voltage
Note:
• If the drive detects this error, the terminal set to H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm] will activate.
• Set o4-24 [bAT Detection Selection] to enable/disable bAT detection.
130
Causes
The analog input source is defective or broken.
The parameter setting is H3-xx ≠ B [MFAI Function
Selection ≠ PID Feedback].
Causes
• PI Auxiliary Feedback is less than the YF-06 [PI
Aux Control Wake-up Level] setting, and the drive
is stopped or running as a Lag drive.
Causes
The digital input set to interlock is open
Causes
The emergency override bypass input is active
Causes
The restart delay is active and the drive received a
Run command.
Causes
The motor is disconnected from the load
Causes
The phase rotation is incorrect while Z1-52 = 1 in
Bypass Mode.
Causes
The drive is running in reverse and it received a
Remote Transfer command.
Causes
When auto transfer is enabled, the drive detects a
fault and it cannot transfer while it is running in
reverse.
Causes
The analog input source is defective or broken.
Causes
The analog input from the terminal set to H3-xx = 27
[MFAI Function Selection = PI Auxiliary Control
Feedback Level] is more than 21 mA or less than 3
mA for longer than 1 s.
Causes
The keypad battery voltage is low.

Possible Solutions
Make sure that you install the PID Feedback source and it operates
correctly.
Set H3-xx = B to use the analog input source for PID Feedback.
Possible Solutions
• Make sure that the YF-06 setting is correct.
• Wait for the PI Auxiliary Feedback to recover.
Possible Solutions
Make sure that the damper is functioning correctly. The damper
could be opening and the switch could be open.
Possible Solutions
This is usually an intentional emergency run state. Check the digital
inputs for setting 25, then check the physical digital input terminal
DI-xx to see why it is closed.
Possible Solutions
This is not an alarm. It is information to show that the drive is not
running. When you remove the Run command to the drive, the
AL09 alarm will go away.
Possible Solutions
Replace the belt or coupling between the motor and the load. If the
bypass detected this alarm incorrectly, make sure that parameters
Z1-31 to Z1-36 are correct for your application.
Possible Solutions
Make sure that the sequence (phase rotation) of the input wiring to
the bypass package is correct.
Possible Solutions
This is not an alarm. It is information to show that the bypass cannot
remote transfer when the drive is running in reverse.
Possible Solutions
This is not an alarm. It is information to show that the drive cannot
auto transfer when reverse run is active.
Possible Solutions
Make sure that you install the Auxiliary PI Feedback source and it
operates correctly.
Possible Solutions
Repair transducer or wiring.
Possible Solutions
Replace the keypad battery.
