Table 88 - FLT Mxx Fault Codes
Four-character Display Message Logix Designer Fault Message Problem or Symptom Potential Cause Possible Resolution
FLT M01…SELF SENSING Self-sensing Startup Fault
The self-sensing commutation start-up
algorithm failed.
Extremely light or heavy load
on the motor.
Clear faults and re-try.
Mechanical obstruction.
• Reduce friction.
• Check for mechanical obstruction.
FLT M02…MOTOR VOLTAGE Motor Voltage Mismatch
Motor voltage incompatible with drive
voltage.
Check the Logix Designer
configuration.
Correct the Logix Designer
configuration.
Wrong motor connected to
drive.
Connect appropriate motor to drive.
FLT M04…MTR FDBK FILTER nn
(Kinetix 6500 drives only)
Motor Feedback Filter
Excessive levels of noise have been detected
by the digital feedback filter. The nn field is
defined as follows:
01: Sine or A channel
02: Cosine or B channel
The motor feedback wiring is
open, shorted, or missing.
• Use shielded cables with twisted
pair wires.
• Route the feedback away from
potential noise sources.
• Check the system grounds.
• Replace the motor/encoder.
FLT M04…AUX FDBK FILTER nn
(Kinetix 6500 drives only)
Aux Feedback Filter
The auxiliary feedback wiring is
open, shorted, or missing.
FLT M05…MTR FDBK BATT LOSS Motor Encoder Battery Loss
The battery voltage on a battery-backed
motor encoder is low enough such that
absolute position is no longer available.
Weak battery or poor battery
connection.
•Replace battery.
• Check battery connection.
FLT M06…MTR FDBK BATT LOW Motor Encoder Battery Caution
The battery voltage on a battery-backed
motor encoder is below a caution level.
FLT M07…MTR INCR LOSS Motor Incremental Position Loss
The periodic check of the incremental
encoder position against the absolute
encoder position or Hall edges (when
available) indicates they are out of
tolerance.
The motor feedback wiring is
open, shorted, or missing. • Check motor encoder wiring.
• Run Hookup test in the Logix
Designer application.
FLT M07…AUX INCR LOSS Aux Incremental Position Loss
The auxiliary feedback wiring is
open, shorted, or missing.
FLT M10…CTRL OVERTEMP FL Control Module Overtemperature
The control module temperature has
exceeded its limit.
Cabinet ambient temperature
has exceeded 50 °C (122 °F).
Reduce cabinet ambient
temperature.
FLT M11…CTRL OVERTEMP UL
(Kinetix 6500 drives only)
Control Module Overtemperature The control module temperature has exceeded a user limit.
FLT M12…POWER CYCLE FL Pre-charge Overload
The converter estimates that the pre-
charge circuit has exceeded its limit due to
excessive power cycling.
The DC bus power has been
cycled too frequently.
Limit power cycles to two per minute
maximum.
FLT M13…POWER CYCLE UL
(Kinetix 6500 drives only)
Pre-charge Overload
The converter estimates that the pre-
charge circuit is approaching its user-
defined limit due to excessive power
cycling.
FLT M14…CURR FDBK OFFSET Excessive Current Feedback Offset Current feedback hardware fault detected. Replace the power module.
FLT M15…REGEN PWR SUPPLY Regenerative Power Supply Fault
The hardware Regeneration OK input was
deactivated while the drive was enabled.
Regen unit faulted. Reset faulted regen unit.
FLT M19…DC BUS LIMIT DC Bus Limited Position Error
During a DC bus limit condition, the
position error exceeded a user limit for a
programmable period of time.
Excessive load drawn from DC
bus by application.
Modify application to reduce loading
on DC Bus
.
In
crease converter size to provide
additional bus capacity.
FLT M25…COMMON BUS DC Common Bus Fault
AC Power was detected by the drive while
configured for Common Bus Follower
operation.
Improper configuration or
connection.
Check IAM power configuration and
wire accordingly.
FLT M26…RUNTIME ERROR Runtime Drive Error The drive firmware encountered an unrecoverable runtime error.
Cycle control power.
Replace Module
FLT M27…BACKPLANE COMM Backplane COM
Communication over the backplane
detected a problem.
Electrical Noise. Cycle control power.
Poor module connection.
With power off, reseat power module
in rail and control module in power
module.
Faulty module. Replace module.
