Error
Code Text
Message Possible Cause Action/Solution
Motor Overtemperature
Motor thermal switch trips due to:

High motor ambient temperature,
and/or

Excessive current

Operate within (not above) the continuous
torque rating for the ambient
temperature.

Lower ambient temperature, or increase
motor cooling.
Motor wiring error Check motor wiring.
Incorrect motor selection Verify the proper motor has been selected.
IPM Error
Motor cables shorted Verify continuity of motor power cable and
connector.
Motor winding shorted internally Disconnect motor power cables from the
motor. If the motor is difficult to turn by hand,
it may need to be replaced.
Operation above continuous power
rating

Verify ambient temperature is not too
high.

Operate within the continuous power
rating.

Reduce acceleration rates.
Drive has a bad IPM output, short circuit,
or overcurrent Remove all power and motors connections,
then perform a continuity check from the DC
bus to the U, V, and W motor terminals. If
continuity exists, check for wire fibers
between terminals, or send drive in for repair.
Bus Undervoltage
Low AC line/AC power input

Verify voltage level of the incoming AC
power.

Check AC power sources for glitches or
line drop.

Install uninterruptible power supply (UPS)
on the AC input.
Attempted to enable drive without main
power active. Apply main power before enabling drive.
Bus Overvoltage
Excessive regeneration of power (i.e.,
When the motor is driven by an external
mechanical force, it may regenerate too
much peak energy through the drive’s
power supply and the drive faults to save
itself from an overload.)

Verify shunt circuit.

Adjust motion profile to stay within the
range of the regenerative resistor.

Replace regenerative transistor.

Replace drive.
Excessive AC input voltage Verify input is within specification.
