oH
Heatsink overheat.
oL1
Motor overload – motor
electronic thermal overload
detected.
Check the size of the load,
the V/f setting (
n24 to
n30 ), accel setting (n20
or
n22 ), the intake air
temperature (must not
exceed 113°F/45°C), or the
cooling fan.
Check the size of the load,
electronic thermal motor
protection setting (
n32 ), or
the V/f setting (
n24 to
n30 ). Set motor rated
current value (
n31 )
according to motor
nameplate value.
oL2
Drive overload – drive
electronic thermal overload
detected.
oL3
Overtorque detection – drive
motor current exceeds the
set value for longer than
detection time.
Check the size of the load,
or the V/f setting (
n24 to
n30 ). Re-check the drive
capacity.
Check the driven machine
and remove the overload
condition, or increase the
value in
n51 to the
machine’s allowable value.
E F1
E F2
E F3
External faults – drive
receives an external fault
input from control circuit
terminal.
Check multi-function input
terminals S1, S2 and S3.
F00
CPF-00 – initial memory fault
is detected.
F01
CPF-01 – ROM fault is
detected.
Turn the power supply off,
then on again. If the fault
remains, replace the drive.
