Probable cause and remedyFault name and
meaning
OL3 Overtorque detection
(OL3)
There has been a current
or torque the same as or
greater than the setting
in n098 for overtorque
detection level and that
in n099 for overtorque
detection time. A fault
has been detected with
n096 for overtorque
detection function
selection set to 2 or 4.
· The mechanical system is locked or has a failure.
® Check the mechanical system and correct the
cause of overtorque.
· The parameter settings were incorrect.
® Adjust the n098 and n099 parameters
according to the mechanical system.
Increase the set values in n098 and n099.
efj External fault j (EFj)
An external fault has
been input from a
multi-function input.
A multi-function input 1 to
7 set to 3 or 4 has
operated. The EF
number indicates the
number of the
corresponding input (S1
to S7).
· An external fault was input from a multi-function
input.
® Remove the cause of the external fault.
· The sequence is incorrect.
® Check and change the external fault input
sequence including the input timing and NO or
NC contact.
f00 Digital Operator
transmission fault 1
(F00)
No communications were
possible with the Digital
Operator for 5 s or more
after the Inverter had
been turned ON.
· The Digital Operator may not be mounted prop-
erly.
® Turn OFF the Inverter, dismount and mount the
Digital Operator, and turn ON the Inverter.
· The Digital Operator has a failure.
® Change the Digital Operator.
· The Inverter has a failure.
® Change the Inverter.
f01 Digital Operator
transmission fault 2
(F01)
A transmission fault
continued for 5 s or more
after communications
with the Digital Operator
had failed.
· The Digital Operator may not be mounted prop-
erly.
® Turn OFF the Inverter, dismount and mount the
Digital Operator, and turn ON the Inverter.
· The Digital Operator has a failure.
® Change the Digital Operator.
· The Inverter has a failure.
® Change the Inverter.
