14041 NTC-T Open Flt
NTC-T Open Fault. The heatsink
temperature sensor (NTC) for the T (L3)
phase of the power module indicates an
open circuit (the value has fallen below
–40°C). The sensor or circuit is faulty. See
the corresponding parameter in Port 14
[Ln HeatsinkTempT].
Replace the Ln power module. See the
hardware service manual, publication
750-TG100, for the replacement
procedure.

Additional Fault Action. Fault opens
main circuit breaker: Yes. Fault can
automatically reset: No. Emergency

14042 T OverTemp Flt
Heatsink-T OverTemp Fault. The
temperature in the heatsink for the T (L3)
phase of the power module has risen
above 118°C. Possible causes include
loads that require too much current and
power, improper derating for temperature
and altitude, and obstructed airflow. See
the corresponding parameter in Port 14
[Ln HeatsinkTempT].
Verify that the drive is sized and
derated correctly. Check the condition
of cabinet air filters. Verify adequate
airflow and the ambient temperature is
within specification. See the technical
data, publication 750-TD100.

Fault
14044 T LowTemp Flt
Heatsink-T LowTemp Fault. The
temperature in the heatsink for the T (L3)
phase of the power module has fallen
below –30°C. The most common cause is
an ambient temperature that is too low for
operation. See the corresponding
parameter in Port 14 [Ln
HeatsinkTempT].
Verify that the ambient temperature is
within specification. See the technical
data, publication 750-TD100.

Fault
14046 Jnt OverTemp Flt
Junction OverTemp Fault. The transistor
junction temperature of the power module
has exceeded the Fault Temperature
which is 155°C for 3.5 sec or 165°C.
Possible causes include loads that
require too much current and power,
improper derating for temperature and
altitude, and obstructed airflow. See the
corresponding parameter in Port 14 [Ln
IGBT Temp] Note: This temperature may
rise/fall faster than the update rate of the
drive.
Verify that the drive is sized and
derated correctly. Verify converter
configuration for proper transformer
nameplate data and gains.
