Warning

Fault contacts
do not change
state.

OP! (parameters setting
error when the parameters
setting is performed through
the MEMOBUS
communications)
OP1: Two or more values are

set for multi-function
input selection.
(parameters n36 to
n39)

OP2: Relationship among

V / f parameters is not
correct.
(parameters n09, n11,
n12, n14)

OP3: Setting value of motor

rated current exceeds
120% of inverter rated
current. (parameter
n32)

OP4: Upper/lower limit of

frequency reference is
reversed. (parameters
n30, n31)

OP5: Setting values of jump

frequencies 1 and 2 are
not appropriate.
(parameters n49 to
n50)

OP9: Carrier frequency

setting is incorrect.
(parameter n46)

Check the setting
values.

OL 3 (Over torque detection)
Motor current exceeded the
preset value in parameter
n98.

Reduce the load and
expand the accel/decel
time.

Inverter receives LOCAL/
REMOTE select command or
communication/control circuit
