6.5 Faults
Code Name
FB26 Option on Drive Detected
Note:
Do a Fault Reset to clear the fault.
Code Name
FB27 Drive Hardware Fault (CPFx oFx)
Note:
Do a Fault Reset to clear the fault.
Code Name
FB28 Drive Faulted
Note:
Do a Fault Reset to clear the fault.
Code Name
FB30 Conflicting SW Check UB-99
Note:
Do a Fault Reset to clear the fault.
Code Name
FDBKL WIRE Break
Note:
• Do a Fault Reset to clear the fault.
• If the drive detects this fault, 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 fault.
Code Name
GF Ground Fault
Note:
• The drive detects this fault if a current short to ground was more than 50% of rated current on the output side of the drive.
• Do a Fault Reset to clear the fault.
• L5-08 [Fault Reset Enable Select Grp2] disables the Auto Restart function.

Causes
A communications option PCB is in drive terminal
CN5.
Causes
There is a CPFxx or oFA fault on the drive.
Causes
A generic fault that shows there is a drive fault when
the exact fault is unknown.
Causes
The bypass controller software version does not align
with the drive software version.

<1> This combination is allowed. Set Z1-99
[Maximum Drive SW Ver] to the Drive Software
Version number shown in the table.
Causes
The analog input from the terminal set for PID
Feedback [H3-xx = B] is more than 21mA or less
than 3mA for longer than 1 s in these conditions:
• b5-82 = 2 [Feedback Loss 4～20mA Detect Sel =
Fault]
• b5-01 ≠ 0 [PID Mode Setting ≠ Disabled]
• H3-01 or H3-09 = 2 [Terminal A1/A2 Signal Level
Selection = 4 to 20 mA]
Causes
Overheating caused damage to the motor or the motor
insulation is not satisfactory.
The motor main circuit cable is contacting ground to
make a short circuit.
An increase in the stray capacitance of the cable and
the ground terminal caused an increase in the leakage
current.
There was a problem with the drive hardware.

Possible Solutions
Remove the option from the drive and install it on terminal CN5 on
the bypass controller.
Possible Solutions
Remove the cause of the fault on the drive.
Possible Solutions
Possible Solutions
1. View monitor Ub-18 to determine the bypass controller
software version.
2. View monitor U1-25 to determine the drive software version.
3. Refer to .

Yes
Yes
Possible Solutions
Make sure that you install the PID feedback source and it operates
correctly.
Possible Solutions
Measure the motor insulation resistance, and replace the motor if
there is electrical conduction or unserviceable insulation.
• Examine the motor main circuit cable for damage, and repair
short circuits.
• Measure the resistance between the motor main circuit cable and
the ground terminal. If there is electrical conduction, replace the
cable.
• If the wiring length of the cable is more than 100 m, decrease the
carrier frequency.
• Decrease the stray capacitance.
Replace the control board or the drive. For information about
replacing the control board, contact Yaskawa or your nearest sales
representative.
