(External fault)
Inverter receives an external
fault input from control circuit
terminal.
EF0: External fault reference
through MEMOBUS
communications
EF1: External fault input
command from control
circuit terminal S1
EF2: External fault input
command from control
circuit terminal S2
EF3: External fault input
command from control
circuit terminal S3
EF4: External fault input
command from control
circuit terminal S4
EF5: External fault input
command from control
circuit terminal S5
EF6: External fault input
command from control
circuit terminal S6
EF7: External fault input
command from control
circuit terminal S7
Check the external
circuit (sequence).
CPF-00
Inverter cannot communicate
with the digital operator for 5
sec. or more when power is
turned ON.
Cycle power after
checking the digital
operator is securely
mounted.
If the fault remains,
replace the digital
operator or inverter.
CPF-01
Transmission fault occurred
for 5 sec. or more when
transmission starts with the
digital operator.
Cycle power after
checking the digital
operator is securely
mounted.
If the fault remains,
replace the digital
operator or inverter.
CPF-04
EEPROM fault of inverter
control circuit is detected.
• Record all parameter
data and initialize the
parameters. (Refer
to page 32 for
parameter
initialization)
• Cycle power.
If the fault remains,
replace the inverter.
