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.
Blinking
SER (Sequence error)
Inverter receives LOCAL/
REMOTE select command or
communication/control circuit
terminal changing signals
from the multi-function
terminal while the inverter is
outputting. Check the external
circuit (sequence).
