Option Card External Fault
EF0
An external fault condition is present.
• Remove the cause of the external fault.
• Remove the external fault input from the PLC.
Check the PLC program and correct problems.
External Fault (input terminal S1)
EF1
External fault at multi-function input terminal S1.
External Fault (input terminal S2)
EF2
External fault at multi-function input terminal S2.
External Fault (input terminal S3)
EF3
External fault at multi-function input terminal S3.
External Fault (input terminal S4)
EF4
External fault at multi-function input terminal S4.
External Fault (input terminal S5)
EF5
External fault at multi-function input terminal S5.
External Fault (input terminal S6)
EF6
External fault at multi-function input terminal S6.
External Fault (input terminal S7)
EF7
External fault at multi-function input terminal S7.
External Fault (input terminal S8)
EF8

• Properly connect the signal lines to the terminals assigned for external fault detection
(H1-oo = 20 to 2B).
• Reconnect the signal line.
• Check for unused terminals set for H1-oo = 20 to 2B (External Fault).
• Change the terminal settings.
EEPROM Write Error
Err
Data cannot be written to the EEPROM
• Press "ENTER" on the digital operator.
• Correct the parameter setting.
• Cycle power to the drive.
• If the problem continues, replace the control board or the entire drive. Contact Yaskawa or a Yaskawa
representative for instructions on replacing the control board.
