Forward/Reverse Run Command Input Error
EF
Both forward run and reverse run closed simultaneously for longer than 0.5 s.
Check the forward and reverse command sequence and correct the problem.
Note: When minor fault EF detected, motor ramps to stop.
Option Card External Fault
An external fault condition is present.
• Remove the cause of the external fault.
• Remove the external fault input from the PLC.
External Fault (Input Terminal S1)
External fault at multi-function input terminal S1.
External fault (input terminal S2)
External fault at multi-function input terminal S2.
External fault (input terminal S3)
External fault at multi-function input terminal S3.
External fault (input terminal S4)
External fault at multi-function input terminal S4.
External fault (input terminal S5)
External fault at multi-function input terminal S5.
External fault (input terminal S6)
External fault at multi-function input terminal S6.
External fault (input terminal S7)
External fault at multi-function input terminal S7.
External fault (input terminal S8)
External fault at multi-function input terminal S8.
Remove the cause of the external fault and reset the multi-function input value.
• Ensure the signal lines have been connected properly to the terminals assigned for external fault detection
(H1-oo = 2C to 2F).
• Reconnect the signal line.
• Check if the unused terminals have been set for H1-oo = 2C to 2F (External Fault).
• Change the terminal settings.
Emergency Override Forward Run
Open H1-oo = AF if the emergency condition is no longer present
Emergency Override Reverse Run
Open H1-oo = B0 if the emergency condition is no longer present
