Phase
WNegToGrnd
Phase W Negative To Ground. A phase
to ground fault has been detected
between the drive and motor in this
phase.
Rotate U/T1, V/T2, W/T3 connections.
If the problem follows the wire, suspect
a field wiring problem. If no change,
suspect a problem with the drive.

causes include loads that require too
much current and power, improper
derating for temperature and altitude, and
obstructed airflow.
Verify that the drive is sized and
derated correctly. Check the condition
of cabinet air filters.

Excessive Load
Excessive Load. The motor did not come
up to speed in the allotted time during
Autotune.
Decrease load on the motor. Uncouple
motor. For induction motors, run a
static MotorID test. For systems with
encoders, perform a Direction test first.

AutoTune Aborted
Autotune Aborted. The Autotune function
was interrupted. This interruption was the
result of manual cancellation or a fault.
If not intended, ensure no stop signal is
issued during an autotune. See

PrechargeOpenFlt
Precharge Open Fault. The internal
precharge-circuity-bypass relay (for
drives) or main contactor (for CBIs) was
commanded to open while the drive was
running (PWM was active) due to low DC
bus voltage. The internal fault latch is
automatically cleared when PWM is
disabled.
Investigate low DC bus voltage or the
reason the drive entered precharge.
