hardware in the power module has
detected a ground fault event. Ground
current is greater than 25% of the power
module rating.

Fault
14027 Bus OV Flt
Bus OV Fault. The DC bus voltage has
exceeded the maximum value. Monitor
DC bus voltage in parameter 0:3 [DC Bus
Volts]. Possible causes include:
configuration of line side converter,.
configuration of DC bus regulator, high
inertia loads, and fast decel times.
For regenerative converters, verify the
regeneration configuration parameters.
For non-regenerative converters,
increase decel time or provide a means
to dissipate excess energy.

Fault
14028 NTC-R Short Flt
NTC-R Short Fault. The heatsink
temperature sensor (NTC) for the R (L1)
phase of the power module indicates a
short circuit (the value has risen above
150°C). The sensor or circuit is faulty. See
the corresponding parameter in Port 14
[Ln HeatsinkTempR].
Replace the Ln power module. See the
hardware service manual, publication
750-TG100, for the replacement
procedure.

14029 NTC-R Open Flt
NTC-R Open Fault. The heatsink
temperature sensor (NTC) for the R (L1)
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

Fault
14030 R OverTemp Flt
Heatsink-R OverTemp Fault. The
temperature in the heatsink for the R (L1)
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 HeatsinkTempR].
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.

14032 R LowTemp Flt
Heatsink-R LowTemp Fault. The
temperature in the heatsink for the R (L1)
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
HeatsinkTempR].
Verify that the ambient temperature is
within specification. See the technical
data, publication 750-TD100.
