Troubleshoot the Kinetix 6200 and Kinetix 6500 Drive System Chapter 8
FLT S06…MTR OVERTEMP UL nn
(Kinetix 6500 drives only)
Motor Overtemperature
The motor thermostat, motor
thermistor, or encoder temperature
sensor indicates that the motor factory
temperature limit has been exceeded.
The nn sub-code is defined as follows:
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.
01:Motor Thermostat or Thermistor. Motor wiring error.
Check motor wiring at motor feedback (MF)
connector.
02:Encoder Temperature Sensor. Incorrect motor selection. Verify the proper motor has been selected.
FLT S07…MTR OVERLOAD FL Motor Thermal Protection
The thermal model for the motor
indicates that the temperature has
exceeded 110% of its rating.
The machine duty cycle
requires an RMS current
exceeding the continuous
rating of the motor.
Change the command profile to reduce speed or
increase time.
FLT S08…MTR OVERLOAD UL
(Kinetix 6500 drives only)
Motor Thermal Protection
The thermal model for the motor
indicates that the temperature has
exceeded a user programmable limit.
FLT S10…INV OVERCURRENT IPM Fault
The IPM fault output indicates that the
power transistors were turned off
because of overcurrent,
overtemperature, or power supply
problems.
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.
The drive temperature is too
high.
• Check for clogged vents or defective fan.
• Make sure cooling is not restricted by
insufficient space around the unit.
• Verify ambient temperature is not too high.
Operation above continuous
power rating and/or product
environmental ratings.
• Operate within the continuous power rating.
• Reduce acceleration rates.
• Reduce deceleration rates.
The drive has a short circuit,
overcurrent, or failed
component.
Remove all power and motor connections, and
preform a continuity check from the DC bus to
the U, V, and W motor outputs. If a continuity
exists, check for wire fibers between terminals,
or send drive in for repair.
FLT S11…INV OVERTEMP FL Inverter Overtemperature Inverter thermal switch tripped.
IAM or AM power module
fan failed.
Replace the failed module.
The cabinet ambient
temperature is above rating.
Check the cabinet temperature.
The machine duty cycle
requires an RMS current
exceeding the continuous
rating of the inverter.
Change the command profile to reduce speed or
increase time.
The airflow access to the
drive system is limited or
blocked.
Check airflow and re-route cables away from
the drive system.
FLT S13…INV OVERLOAD FL Inverter Thermal Protection
The thermal model for the power
transistors indicates that the
temperature has exceeded 110% of its
rating.
The machine duty cycle
requires an RMS current
exceeding the continuous
rating of the inverter.
Change the command profile to reduce speed or
increase time.
FLT S14…INV OVERLOAD UL
(Kinetix 6500 drives only)
Inverter Thermal Protection
The thermal model for the power
transistors indicates that the
temperature has exceeded the user-
programable limit.
FLT S16…GROUND CURRENT Ground Fault
Excessive ground current was detected
in the converter.
Wiring error.
•
C
heck motor power wiring.
• Check input power wiring.
Motor internal ground short. Replace motor.
Internal malfunction.
Disconnect motor power cable from drive and
enable drive with current limit set to 0. If fault
clears, then a wiring error or motor internal
anomaly exists. If fault remains, call your sales
representative.
