Probable cause and remedy
Fault 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.
ef
j
External fault
j
(EF
j
)
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.
·
