EF0 Option Card External FaultAn external fault condition is present.Cause Possible SolutionAn external fault was received fromthe PLC with other than F6-03 = 3“alarm only” (the drive continuedto 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.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 S7Cause Possible SolutionAn external device has tripped analarm 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 assignedfor external fault detection (H1-oo = 20 to 2F).• Reconnect the signal line.Incorrect setting of multi-functioncontact inputs.• Check if the unused terminals set for H1-oo = 20 to 2F (External Fault).• Change the terminal settings.Err EEPROM Write ErrorData does not match the EEPROM being written to.FbHExcessive PID FeedbackPID feedback input is greater than the level set b5-36 for longer than the time setto b5-37. To enable fault detection, set b5-12 = “2” or “5”.FbLPID Feedback LossThis fault occurs when PID Feedback Loss Detection is programmed to fault(b5-12 = 2) and the PID Feedback < PID Feedback Loss Detection Level (b5-13)for the PID Feedback Loss Detection Time (b5-14).5.2 Fault Detection134 YASKAWA ELECTRIC TOEP C710606 47A YASKAWA AC Drive – V1000 Quick Start Guide
