Troubleshooting 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.
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 controller.
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 controller.
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.
