Yaskawa J1000 Compact Vector Control Drive - Manual (Page 137)

Digital Operator Display Fault Name
Cause Possible Solution
An external fault was received from
the PLC with other than F6-03 = 3
“alarm only” (the drive continued
to run after external fault).
• Remove the cause of the external fault.
• Remove the external fault input from the PLC.
Problem with the PLC program. Check the PLC program and correct problems.
Digital Operator Display Fault Name
EF1
External Fault (input terminal S1)
External fault at multi-function input terminal S1.
EF2
External Fault (input terminal S2)
External fault at multi-function input terminal S2.
EF3
External Fault (input terminal S3)
External fault at multi-function input terminal S3.
EF4
External Fault (input terminal S4)
External fault at multi-function input terminal S4.
EF5
External Fault (input terminal S5)
External fault at multi-function input terminal S5.
EF6
External Fault (input terminal S6)
External fault at multi-function input terminal S6.
EF7
External Fault (input terminal S7)
External fault at multi-function input terminal S7
Cause Possible Solution
An external device has tripped an
alarm function.
Remove the cause of the external fault and reset the fault.
Wiring is incorrect.
• Ensure the signal lines have been connected properly to the terminals assigned
for external fault detection (H1- = 20 to 2F).
• Reconnect the signal line.
Incorrect setting of multi-function
contact inputs.
• Check if the unused terminals set for H1- = 20 to 2F (External Fault).
• Change the terminal settings.
