Fault name and meaning Probable cause and remedy
EF
„
External fault
„
( E F
„
)
An external fault has been
input from a multi-function
input.
A multi-function input 1, 2, 3,
or 4 set to 3 or 4 has
operated. The EF number
indicates the number of the
corresponding input (S2 to
S5).
•
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)
An initial memory fault has
been detected
•
The internal circuitry of the Inverter has a fault.
~
Turn the Inverter
o f f
and on.
~
Replace the Inverter if the same fault occurs again.
FO 1
Digital Operator
transmission fault 2 (F01)
A ROM fault has been
detected.
•
The internal circuitry of the Inverter has a fault.
~
Turn the Inverter
o f f
and on.
~
Replace the Inverter if the same fault occurs again.
FO4 Initial memory fault (F04)
An error in the built-in
EEPROM of the Inverter has
been detected.
•
The internal circuitry of the Inverter has a fault.
~
Initialize the Inverter with n01 set to 8 or 9 and turn the
Inverter
o f f
and on.
~
Replace the Inverter if the same fault occurs again.
FO5 Analog-to-digital converter
fault (F05)
An analog-to-digital converter
fault has been detected.
• The internal circuitry of the Inverter has a fault.
->
Turn the Inverter
o f f
and on.
~
Replace the Inverter if the same fault occurs again.
FG1
Digital Operator fault (F07)
An error in the built-in control
circuit of the Digital Operator
has been detected.
•
The internal circuitry of the Digital Operator has a fault.
~
Turn the Digital Operator
o f f
and on.
~
Replace the Digital Operator if the same fault occurs
again.
STP
Emergency stop (STP)
An emergency stop alarm is
input to a multi-function input.
(A multi-function input 1, 2, 3,
or 4 set to 19 or 21 has
operated.)
• An emergency stop alarm is input to a multi-function input.
->
Remove the cause of the fault.
•
The sequence is incorrect.
~
Check and change the external fault input sequence
including the input timing and NO or NC contact.
OFF
Power supply error
•
I n s u f f i c i e n t
power supply
voltage
•
Control power supply fault
•
Hardware fault
•
No power supply is provided.
->
Check and correct the power supply wire and voltage.
•
T e r m i n a l
screws are loosened.
->
Check and tighten the terminal screws.
•
The Inverter is damaged.
->
Replace the Inverter.
