Possible cause/corrective actions

Contents

OL2 (Inverter Overload)

Inverter overload protection op-
erates because of electronic
overload thermal.

Correct load size, operation pattern or V/f set
value. Recheck the inverter capacity.

OL3 (Overtorque Detec-
tion)

Motor current exceeding set
value is applied because of ma-
chine fault or overload.

Check the machine using status and remove
the cause. Or increase the set value up to
the allowable value.

EF3 (External Fault)

Inverter accepts fault contact
signal input from external cir-
cuit.

Check the external circuitry (sequence).

CPF (Control Function
Fault)

-

,

(see note 1)

Inverter control functions are
broken down.

Turn off the power supply once and then turn
it on again. If the fault still exists, replace the
inverter.

CPF-00

(

)

Initial memory fault is detected.

Turn off the power supply once and turn it on
again. If the fault still exists, replace the in-
verter.

CPF-01

(

)

Transmission error or ROM
fault is detected.

Turn off the power supply once and turn it on
again. If the fault still exists, replace the in-
verter.

CPF-04

(

)

Constant fault is detected.

Record all data, and then make initialization.
Turn off the supply once and turn it on again.
If the fault still exists, replace the inverter.

CPF-05

(

)

AD converter fault is detected.

Turn off the power supply once and turn it on
again. If the fault still exists. replace the in-
verter.

CPF-07

(

)

Thermistor fault is detected.

Replace the inverter.

Possible cause/corrective actions

EF (Simultaneous Input of
FWD and REV com-
mands)

blinks.

Both FWD and REV commands
are “closed” for 500 ms or
more.

Check the sequence circuit

BB (External Baseblock)

External baseblock signal is ac-
cepted. (Pay attention since op-
eration restarts by releasing the
external baseblock signal.)

Check the sequence circuit

UV (Main Circuit Under-
voltage)

 

blinks.

Main circuit DC voltage is re-
duced less than detection level
when inverter is not outputting.

Check power supply voltage or check that
power supply terminal screws are tightened
well.

OL3 (Overtorque Detec-
tion)

blinks.

Inverter output current exceeds
overtorque detection level.

Check the machine using status and remove
the cause. Or increase the set value.
