EF
Cause
Sequence error
Digital Operator Display
EF0
Cause
An external fault was received from the PLC
with F6-03 = 3 (causing the drive to continue
running when an external fault occurs).
There is a problem with the PLC program.

Possible Solutions
⇒Check the operation sequence.
Forward/Reverse Run Command Input Error
Both forward run and reverse run closed simultaneously for over 0.5 s.
Possible Solutions
⇒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.
Possible Solutions
⇒Remove the cause of the external fault.
⇒Remove the external fault input from the PLC.
⇒Check the PLC program and correct problems.
