Chapter 8 Troubleshooting the Kinetix 6200 and Kinetix 6500 Drive System
FLT S16…GROUND CURRENT Ground Fault
Excessive ground current was detected
in the converter.
Wiring error. Check motor power wiring.
Motor internal ground short. Check input power wiring.
Internal malfunction. Replace motor.
FLT S18…CONV OVERTEMP FL Converter Overtemperature Converter thermal switch tripped.
Excessive heat exists in the
power circuitry.
• Reduce acceleration rates.
• Reduce duty cycle (ON/OFF) of
commanded motion.
• Increase time permitted for
motion.
• Use larger IAM power module.
• Check for clogged vents or
defective fan.
• Make sure cooling is not
restricted by insufficient space
around the unit.
FLT S20…CONV OVERLOAD FL Converter Thermal Protection
The thermal model for the converter
indicates that the temperature has
exceeded its rating.
Excessive current is being
drawn by the power
circuitry.
• Reduce acceleration rates.
• Reduce duty cycle (ON/OFF) of
commanded motion.
• Increase time permitted for
motion.
• Use larger IAM power module.
FLT S21…CONV OVERLOAD UL
(Kinetix 6500 drives only)
Converter Thermal Protection
The thermal model for the converter
indicates that the temperature has exceeded
a user-programmable limit.
FLT S22…AC POWER LOSS AC Power Loss
All three AC input phases are detected
as absent when an axis is enabled.
Axis was enabled when
main (three-phase) power
was removed.
Disable axis before removing
power.
FLT S23…AC PHASE LOSS nn AC Phase Loss
Some, but not all AC input phases are
detected as absent. The nn sub-code is
defined as follows:
01: L1 is missing.
02: L2 is missing.
03: L3 is missing.
Faulty AC line control
equipment. Check input AC voltage on all
phases.
FLT S25…PRECHARGE FAILURE Pre-charge Failure
The converter pre-charge circuit
detected that the DC bus did not reach
an appropriate voltage level after
charging for a period of time.
Low AC input voltage.
Check input AC voltage on all
phases
Internal malfunction. Call your sales representative.
FLT S29…SHUNT OVERLOAD FL Shunt Thermal Protection
The thermal model for the shunt circuitry indicates that the
temperature has exceeded its rating. • Use a properly sized shunt or
modify duty cycle of the
application.
• System uses internal shunt
and requires external shunt for
additional capacity.
FLT S30…SHUNT OVERLOAD UL
(Kinetix 6500 drives only)
Shunt Thermal Protection
The thermal model for the shunt circuitry indicates that the
temperature has exceeded a user-programmable limit.
FLT S31…SHUNT MODULE Shunt Module Fault
The shunt module in a multi-axis
system has a fault.
Over-temperature fault
indicator on Bulletin 2094
shunt module is steady red.
Refer to Temperature Fault Status
Indicator on
page 211 .
Shunt-fault indicator on
Bulletin 2094 shunt module
is steady red.
Refer to Shunt Fault Status
Indicator on
page 211 .
Bulletin 2094 shunt module
is missing from power rail.
Install missing module on power
rail.
Fill empty slot with slot-filler
module.
