Maintenance Operations
Fault Fault name and meaning
display
%l3
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.
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).
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.
f01
Digital Operator
transmission fault 2 (F01)
A transmission fault continued
for 5 s or more after
communications with the
Digital Operator had failed.
f04
Initial memory fault (F04)
An error in the built-in
EEPROM of the Inverter has
been detected.
f05
Analog-to-digital converter
fault (F05)
An analog-to-digital converter
fault has been detected.
f06
Option Unit fault (F06)
An Option Unit fault was
detected. The Inverter will
detect this error if the output or
verify signal of the Unit has a
fault.
Probable cause and remedy
• 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.
• 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.
• The Digital Operator may not be mounted properly.
→ 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.
• The Digital Operator may not be mounted properly.
→ 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.
• The internal circuitry of the Inverter has a fault.
→ Initialize the Inverter with n001 set to 8, 9, 10, or 11 and
turn the Inverter OFF and ON.
→ Replace the Inverter if the same fault occurs again.
• The internal circuitry of the Inverter has a fault.
→ Turn the Inverter OFF and ON.
→ Replace the Inverter if the same fault occurs again.
• The Option Unit may not be connected properly.
→ Turn OFF the Inverter, dismount and mount the Option
Unit or attachment, and turn ON the Inverter.
• The Option Unit has a failure.
→ Change the Option Unit.
• The attachment has a failure.
→ Change the attachment.
