EEPROM Memory Q2pack Data
Error
There is an error in the EEPROM peripheral circuit. • Re-energize the drive.
• If the fault stays, replace the control board or the drive. For
information about replacing the control board, contact the
manufacturer or your nearest sales representative.
There is a problem with the EEPROM data. Set A1-03 = 2220, 3330 [Init Parameters = 2-Wire Initialization,
3-Wire Initialization] to initialize the drive, then upload the
Q2pack project to the drive again.
Note:
• The drive detects this error if there is an error in the Q2pack program that was saved to EEPROM.
• Do a Fault Reset to clear the fault.

The communication option received an external
fault from the controller.
1. Find the device that caused the external fault and remove the
cause.
2. Clear the external fault input from the controller.
A programming error occurred on the controller
side.
Examine the operation of the controller program.
Note:
• The drive detects this fault if the alarm function on the external device side is operating.
• Do a Fault Reset to clear the fault.
• If the drive detects this fault, it will operate the motor as specified by the stop method set in F6-03 [Comm Ext Flt Select (EF0)].
Code Name Causes Possible Solutions
EF1 External Fault (Terminal DI1)
MFDI terminal DI1 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 DI1.
External Fault [H1-01 = 20 to 2B] is set to MFDI
terminal DI1, but the terminal is not in use.
Correctly set the MFDI.
Note:
Do a Fault Reset to clear the fault.

EF2 External Fault (Terminal DI2)
MFDI terminal DI2 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 DI2.
External Fault [H1-02 = 20 to 2B] is set to MFDI
terminal DI2, but the terminal is not in use.
Correctly set the MFDI.
