H181 Light Alarm Selection 1
H182 Light Alarm Selection 2
H183 Light Alarm Selection 3
H184 Light Alarm Selection 4
If a detected abnormal state represents a minor failure, an alarm (display and general-purpose
output terminal) is output and operation can be continued without inverter trip. When an
minor failure occurs, an alarm icon which designates its occurrence is shown on an LCD
monitor and the WARN. LED blinks. What is to be subjected to this function can be selected
with function codes H181, H182, H183, and H184. If minor failure "LALM" (data = 98) is
assigned to a general-purpose output terminal (function code E20 to E24, E27), minor failure
"LALM" signals are output to the terminal when a minor failure occurs.
The table below lists alarms selectable as minor failure factors.

Name
An error that has occurred in peripheral
equipment turned the external alarm signal THR
ON.
The temperature inside the inverter abnormally
has increased.
Motor temperature calculated with the inverter
output current reached the trip level.
Communications error between the inverter and
an option.
An option judged that an error occurred.
RS-485 communications error between the COM
ports 1 and 2.
Wire connected to terminal [C1] (current input)
is broken.
Error in PID feedback signals
(PID control 1, PID control 2, External PID
control 1 to 3)
Failure of the air circulation DC fan inside the
inverter. (For UL open type rated inverters of 150
HP or above, NEMA/UL TYPE 1 rated ones of
60 HP or above, and NEMA/UL TYPE 12 rated
ones of 150 HP or above)
Early warning before a motor overload
Early warning before a heat sink overheat trip
It is judged that the service life of any one of the
capacitors (DC link bus capacitors and
electrolytic capacitors on the printed circuit
boards) and cooling fan has expired.
Or, failure of the air circulation DC fan inside the
inverter. (NEMA/UL TYPE 12 only)
Analog frequency command was lost.
Warning related to PID control (absolute-value
alarm or deviation alarm)
(PID control 1, PID control 2, External PID
control 1 to 3)
Output torque drops below the low torque
detection level for the specified period.
