5.2 Fault Detection
Cause
An external fault was received from
the PLC with other than F6-03 = 3
"alarm only" (the drive continued
to run after external fault).
Problem with the PLC program.
Cause
An external device has tripped an
alarm function.
Wiring is incorrect.
Incorrect setting of multi-function
contact inputs.

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
Remove the cause of the external fault and reset the fault.
• Ensure the signal lines have been connected properly to the terminals assigned
for external fault detection (H1-oo = 20 to 2F).
• Reconnect the signal line.
• Check if the unused terminals set for H1-oo = 20 to 2F (External Fault).
• Change the terminal settings.
EEPROM Write Error
Err
Data does not match the EEPROM being written to.
Excessive PID Feedback
FbH
PID feedback input is greater than the level set b5-36 for longer than the time set
to b5-37. To enable fault detection, set b5-12 = "2" or "5".
PID Feedback Loss
This fault occurs when PID Feedback Loss Detection is programmed to fault
FbL
(b5-12 = 2) and the PID Feedback < PID Feedback Loss Detection Level (b5-13)
for the PID Feedback Loss Detection Time (b5-14).
