Causes
MFDI terminal S4 caused an external fault through an
external device.
The wiring is incorrect.
External Fault [H1-04 = 20 to 2B] is set to MFDI
terminal S4, but the terminal is not in use.
Causes
MFDI terminal S5 caused an external fault through an
external device.
The wiring is incorrect.
External Fault [H1-05 = 20 to 2B] is set to MFDI
terminal S5, but the terminal is not in use.
Causes
MFDI terminal S6 caused an external fault through an
external device.
The wiring is incorrect.
External Fault [H1-06 = 20 to 2B] is set to MFDI
terminal S6, but the terminal is not in use.
Causes
MFDI terminal S7 caused an external fault through an
external device.
The wiring is incorrect.
External Fault [H1-07 = 20 to 2B] is set to MFDI
terminal S7, but the terminal is not in use.
Causes
There was a problem with the EEPROM hardware.
Electrical interference corrupted the data while it was
writing to the EEPROM of the drive.
Causes
The cooling fan stopped operating correctly.
The circulation fan is damaged.
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 S4.
Correctly set the MFDI.

Possible Solutions
• Re-energize the drive.
• If the fault stays, replace the control board or the drive. Contact
Yaskawa or your nearest sales representative to replace the
board.
• Push ENTER Key.
• Set the parameters again.
Possible Solutions
• Examine cooling fan operation.
• Re-energize the drive.
• Examine U4-03 [Cooling Fan Ope Time] and U4-04 [Cool Fan
Maintenance]. If the performance life of the cooling fan is
expired or if there is damage to the fan, replace the fan.
• Examine circulation fan operation.
• Re-energize the drive.
• Examine U4-03 [Cooling Fan Ope Time] and U4-04 [Cool Fan
Maintenance]. If there is damage to the circulation fan or if the
performance life of the fan is expired, replace the fan.
