This output signal is used to issue a heat sink overheat early warning that enables you to take
a corrective action before an overheat trip

actually happens.
This signal comes ON when the temperature of the heat sink exceeds the "overheat trip
0h1
temperature minus 5°C," and it goes OFF
temperature minus 8°C."
Service life alarm --
LIFE
(Function code data = 30)
This output signal comes ON when it is judged that the service life of any one of capacitors
(DC link bus capacitors and electrolytic capacitors on the printed circuit board) and cooling fan
has expired.
This signal should be used as a guide for replacement of the
