Protective Op-
eration
Output is
turned OFF
and motor
coasts to a
stop.
EF (External fault)
Inverter receives an ex-
ternal fault input from con-
trol circuit terminal.
EF0: External fault ref-
erence through
MEMOBUS com-
munications
EF2: External fault in-
put command from
control circuit ter-
minal S2
EF3: External fault in-
put command from
control circuit ter-
minal S3
EF4: External fault in-
put command from
control circuit ter-
minal S4
EF5: External fault in-
put command from
control circuit ter-
minal S5
Check the external circuit
(sequence).
CPF-00
Initial memory fault has
detected.
Cycle power.
If the fault remains, re-
place the Inverter.
CPF-01
ROM error has detected.
Cycle power.
If the fault remains, re-
place the Inverter.
CPF-04
EEPROM fault of Inverter
control circuit was detect-
ed.
• Record all constant
data and initialize the
constants. (Refer to
page 44 for constant
initialization.)
• Cycle power. If the
fault remains, replace
the Inverter.
CPF-05
AD converter fault was
detected.
Cycle power.
If the fault remains, re-
place the Inverter.
CPF-06
• Option card connec-
tion fault
• A non-corresponding
option card is con-
nected.
Remove power to the In-
verter. Check the connec-
tion of the Digital
Operator. Verify Software
Version No.
CPF-07
Operator control circuit
(EEPROM or A/D con-
verter) fault
Cycle power. If the fault
remains, replace the In-
verter.
CE (MEMOBUS
communications
fault)
Normal reception of com-
munication data is not
possible.
Check the communication
devices or communication
signals.
