Explanation
Status
CAL (MODBUS
communications waiting)
Correct data has not been
received from the PLC
when the parameter
n003 (operation command
selection) is 2 or
n004 (frequency reference
selection) is 6,
and power is turned ON.
OPE
(Parameter setting
error when the parameter
setting is performed
through the MODBUS
communications)
OPE1: Two or more values
are set for multi-
function input
selection.
(parameters n050 to
n056)
OPE2: Relationship among
V / f parameters is not
correct.
(parameters n011,
n013, n014, n016)
OPE3: Setting value of
electronic thermal
standard current
exceeds 150% of
drive rated current.
Warning
(parameter n036)
only.
OPE4: Upper / lower limit
Fault

OPE5: (parameters n083 to
n085)
OPE9: Carrier frequency
setting is incorrect.
(parameter n080)
OL 3 (Overtorque
detection)
Motor current exceeded
the preset value in
parameter n098.
SEr (Sequence error)
Drive receives
LOCAL / REMOTE select
command or
communication / control
circuit terminal changing
signals from the multi-
function terminal while the
drive output is ON.
6-2
Causes and
Corrective Actions
Check communication
devices, and transmission
signals.
Check the setting values.
Reduce the load, and
increase the accel / decel
time.
Check the external circuit
(sequence).
