Troubleshooting the Kinetix 6200 and Kinetix 6500 Drive System Chapter 8
FLT S33…BUS UNDERVOLT FL Bus Undervoltage
With three-phase power present, the
DC bus voltage is below limits.
DC bus voltage fell below the
undervoltage limit while an axis on the
follower power rail was enabled.
DC bus voltage for 460V
system is below 275V.
• Verify voltage level of the
incoming AC power.
• Check AC power source for
glitches or line drop.
• Install an uninterruptible
power supply (UPS) on your AC
input.
• Disable follower axis before
removing power.
FLT S34…BUS UNDERVOLT UL
(Kinetix 6500 drives only)
Bus Undervoltage
The DC bus voltage is measured below a user
limit when the DC bus was expected to be
charged.
FLT S35…BUS OVERVOLT FL Bus Overvoltage
The DC bus voltage is measured above a
factory limit.
Excessive regeneration of
power. Change the deceleration or
motion profile.
When the motor is driven by
an external mechanical
power source, it may
regenerate too much peak
energy through the drive
power supply. The system
faults to save itself from an
overload.
Use a larger system (motor and
drive).
DC bus voltage for 460V
system is over 820V.
Install shunt module.
FLT S38…FUSE BLOWN Blown Fuse (Bus Loss)
A blown fuse was detected in the
power structure.
Blown fuse.
Call your Rockwell Automation
sales representative to return
module for repair.
FLT S41…MTR AQB STATE FL Motor Feedback State Error
The number of illegal state transitions
of the AQB encoder signals has
exceeded a factory limit.
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 S41…AUX AQB STATE FL Aux Feedback State Error
The auxiliary feedback
wiring is open, shorted, or
missing.
FLT S42…MTR AQB STATE UL Motor Feedback State Error
The number of illegal state transitions
of the AQB encoder signals has
exceeded a user limit.
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 S42…AUX AQB STATE UL Aux Feedback State Error
The auxiliary feedback
wiring is open, shorted, or
missing.
FLT S43…MTR FDBK LOSS FL
Feedback Loss
• On sin/cos encoders, the sum of the
square of the sin/cos signals has
been measured below a factory
limit.
• On TTL encoders, the absolute value
of the differential A/B signals is
below a factory limit.
The motor feedback wiring is
open, shorted, or missing.
• Check motor encoder wiring.
• Run Hookup test in
RSLogix 5000 software.
FLT S43…AUX FDBK LOSS FL
The auxiliary feedback
wiring is open, shorted, or
missing.
FLT S44…MTR FDBK LOSS UL

Motor Feedback Loss
• On sin/cos encoders, the sum of the
square of the sin/cos signals has
been measured below a user limit.
• On TTL encoders, the absolute value
of the differential A/B signals is
below a user limit.
The motor feedback wiring is
open, shorted, or missing.
• Check motor encoder wiring.
• Run Hookup test in
RSLogix 5000 software. FLT S44…AUX FDBK LOSS UL
(Kinetix 6500 drives only)
Aux Feedback Loss
The auxiliary feedback
wiring is open, shorted, or
missing.
FLT S45…MTR FDBK COMM FL
Feedback Serial Comms
The number of consecutive missed or
corrupted serial data packets from the
feedback device has exceeded a factory
set limit.
Communication was not
established with an
intelligent encoder.
• Verify motor selection.
• Verify the motor supports
automatic identification.
• Verify motor encoder wiring.
FLT S45…AUX FDBK COMM FL
FLT S46…MTR FDBK COMM UL
(Kinetix 6500 drives only)
Motor Fdbk Serial Comms The number of consecutive missed or
corrupted serial data packets from the
feedback device has exceeded a user
set limit.
Communication was not
established with an
intelligent encoder.
• Verify motor selection.
• Verify the motor supports
automatic identification.
• Verify motor encoder wiring.
