Note: These terminals can be used only from DeviceNet communications.
There are no corresponding external input terminals.
Protective
Operation
Output is
turned OFF
and motor
coasts to a
stop.
EF
(External fault)
Inverter receives an ex-
ternal fault input from
control circuit terminal.
EF0: External fault ref-
erence through
DeviceNet com-
munications
EF1: External fault in-
put command
from control cir-
cuit terminal S1
EF2: External fault in-
put command
from control cir-
cuit terminal S2
EF3: External fault in-
put command
from control cir-
cuit terminal S3
EF4: External fault in-
put command
from control cir-
cuit terminal S4
EF5: External fault in-
put command
from control cir-
cuit terminal S5
(See note.)
EF6: External fault in-
put command
from control cir-
cuit terminal
S6(See note.)
EF7: External fault in-
put command
from control cir-
cuit terminal
S7(See note.)
Check the external cir-
cuit (sequence).
CPF-00
Inverter cannot commu-
nicate with the Digital
Operator for 5 s or more
when power is turned
ON.
Cycle power after con-
firming that the Digital
Operator is securely
mounted. If the fault re-
mains, replace the Digi-
tal Operator or Inverter.
CPF-01
Transmission fault oc-
curred for 5 s or more
when transmission starts
with the Digital Operator.
Cycle power after con-
firming that the Digital
Operator is securely
mounted. If the fault re-
mains, replace the Digi-
tal Operator or Inverter.
CPF-04
EEPROM fault of Invert-
er control circuit was de-
tected.
• Record all constant
data and initialize
the constants.
(Refer to page 52 for
constant initializa-
tion.)
• Cycle power. If the
fault remains,
replace the Inverter.
