OverVoltage
Over Voltage. DC bus voltage exceeded
120% of the peak value of the rated
voltage for the product. (Peak value is the
AC rated voltage multiplied by √2).
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.

Heatsink Under Temperature. Heatsink
temperature sensor is reporting a value
below –18.7°C. (–1.66°F) or the sensor
feedback circuit is open. See parameter

parameter 10:363 [Heatsnk Temp].
Verify that the ambient temperature is
within specification. See the technical
data, publication 750-TD100 for
PowerFlex 755T or publication 750-

Autotune Inertia
Autotune Inertia Out of Range. The motor
or total inertia that is determined by the
Autotune inertia test function is out of
range. This condition only occurs during
an inertia test.
Verify motor nameplate data. Rerun
inertia Autotune.

InvalidLoadRatio
Invalid Load Ratio. The total system
inertia result of the Autotune is less than
the value in parameter 10:900 [Motor
Inertia], which results in a negative load
ratio.
Determine if the value of parameter
10:900 [Motor Inertia] is too high. If
possible, uncouple the motor from the
load and perform the motor inertia
autotune test.

Jnt OverTemp Flt
Junction OverTemp Fault. The transistor
Junction Temperature of the power
module has exceeded the Fault
Temperature (varies by rating). Possible
causes include loads that require too
much current and power, improper
derating for temperature and altitude, and
obstructed airflow.
Verify motor nameplate data and drive
tuning for proper starting torque. Verify
that the drive is sized and derated
correctly. See the technical data,
publication 750-TD100 for PowerFlex
755T or publication 750-TD104 for
PowerFlex 755TS products.
