Detected as
an alarm
only. Fault
contact out-
put is not
activated.
OL3 (Overtorque detec-
tion)
Motor current exceeded the
preset value in constant
n098.
Overtorque detection level
was exceeded because of in-
creased leak current due to
excessively long wiring.
• Reduce the load, and
increase the accelera-
tion/deceleration time.
• Refer to the paragraph
of Carrier Frequency
Selection (n080)14kHz
max on page 94.
• Check the wiring
(increase of current
caused by rare shortcir-
cuit, etc.).
Flashing
SER (Sequence error)
Inverter received Local/Re-
mote Command or communi-
cations/control circuit terminal
changing signals from the
multi-function terminal while
the Inverter output is ON.
Check the following:
• NO/NC contact selection
(constant).
• Wiring is made properly.
• Signal is not input from
the PLC.
Flashing
UL3 (Undertorque de-
tection)
When V/f mode is selected:
The Inverter’s output current
was less than the under-
torque detection level (n118).
When vector mode is select-
ed: The output current or out-
put torque was less than the
detection level (n097 or
n118).
Operation when undertorque
is detected will be determined
by the setting in n117.
• Check the setting in
n118.
• Check the operating con-
ditions, and remove the
cause.
