Causes
There is an error in the EEPROM peripheral circuit.
There is a problem with the EEPROM data.
Causes
There was a fault in the DriveWorksEZ program.
Causes
There was a fault in the DriveWorksEZ program.
Causes
There was a fault in the DriveWorksEZ program.
Causes
The drive detected a watchdog circuit exception
while it received data from the controller.
Causes
The communication option received an external
fault from the controller.
A programming error occurred on the controller
side.
Causes
MFDI terminal S1 caused an external fault through
an external device.
The wiring is incorrect.
External Fault [H1-01 = 20 to 2B] is set to MFDI
terminal S1, but the terminal is not in use.
Causes
MFDI terminal S2 caused an external fault through
an external device.
The wiring is incorrect.
External Fault [H1-02 = 20 to 2B] is set to MFDI
terminal S2, but the terminal is not in use.
Possible Solutions
• 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.
Set A1-03 = 2220, 3330 [Initialize Parameters = 2-Wire
Initialization, 3-Wire Initialization] to initialize the drive, then
upload the DriveWorksEZ project to the drive again.
Possible Solutions
Examine the DriveWorksEZ program and remove the cause of the
fault. This is not a drive fault.
Possible Solutions
Examine the DriveWorksEZ program and remove the cause of the
fault. This is not a drive fault.
Possible Solutions
Examine the DriveWorksEZ program and remove the cause of the
fault. This is not a drive fault.
Possible Solutions
Examine the MECHATROLINK cable connection. If this error

electrical interference as specified by these manuals:
• MECHATROLINK-II Installation Guide (MECHATROLINK
Members Association, manual number MMATDEP011)
• MECHATROLINK-III Installation Manual
(MECHATROLINK Members Association, publication
number MMATDEP018)
Possible Solutions
1. Find the device that caused the external fault and remove the
cause.
2. Clear the external fault input from the controller.
Examine the operation of the controller program.
Possible Solutions
1. Find the device that caused the external fault and remove the
cause.
2. Clear the external fault input in the MFDI.
Correctly connect the signal line to MFDI terminal S1.
Correctly set the MFDI.
Possible Solutions
1. Find the device that caused the external fault and remove the
cause.
2. Clear the external fault input in the MFDI.
