display
Probable cause and remedy
Fault name and Meaning
OP1
(flashing)
Operation error (OP
j
)
(Parameter setting error)
·
The values in n050 through n056 for
multi-function inputs 1 through 7 have
been duplicated.
®
Check and correct the values.
OP2
(flashing)
·
The V/f pattern settings do not satisfy
the following condition.
n016
n014 < n013
n011
®
Check and correct the set value.
OP3
(flashing)
·
The rated motor current set in n036
exceeds 150% of the rated output cur-
rent of the Inverter.
®
Check and correct the set value.
OP4
(flashing)
·
The frequency reference upper limit set
in n036 and the frequency reference
lower limit set in n034 do not satisfy the
following condition.
n033
n034
®
Check and correct the set values.
OP5
(flashing)
·
The jump frequencies set in n083 to
n085 do not satisfy the following condi-
tion.
n083
n084
n085
®
Check and correct the set values.
OP9
(flashing)
·
The carrier frequency set in n080 is
incorrect. An attempt was made to set a
value that is not within a permissible
range.
®
Check and correct the set value.
OL3
(flashing)
Overtorque detection (OL3)
There has been a current or
torque the same as or greater
than the setting in n098 for
overtorque detection level and
that in n099 for overtorque
detection time. A fault has been
detected with n096 for
overtorque detection function
selection set to 1 or 3.
·
The mechanical system is locked or has
a failure.
®
Check the mechanical system and
correct the cause of overtorque.
·
The parameter settings were incorrect.
®
Adjust the n098 and n099 parameters
according to the mechanical system.
Increase the set values in n98 and
n099.
