Troubleshoot the Kinetix 350 Drive
S 02
Motor not configured.
The associated motor has not been
configured for use.
Faulty intelligent encoder or incorrect
motor file.
• Cycle power or reset the drive.
• Check that proper motor has been
selected in Logix Designer
Application.
• Replace motor if faulting continues.
S 03
Feedback not configured.
The associated feedback device has not
been configured for use or the
configuration does not match what is
connected.
Sc05
Safe torque off.
No power or safety circuitry not
configured.
The safety function has disabled the
power structure.
• Apply 24V sources to safety circuit.
• Use jumpers to bypass safety circuit.

Problem or Symptom
Potential Cause
Possible Resolution
F 02
Illegal Hall State
State of Hall feedback inputs is incorrect.
Improper connections.
•
Check wiring of S1,S2, and S3
•
Check the power supply to the
encoder.
F 03
Motor Overspeed
Motor speed has exceeded 125% of maximum rated speed.
•
Check motor wire phasing.
•
Check cables for noise.
•
Check tuning.
F 05
Motor Overtemperature
The motor thermostat, motor thermistor, or
encoder temperature sensor indicates that the
motor factory temperature limit has been
exceeded.
High motor ambient temperature
and/or Excessive Current.
•
Check motor wiring at motor
feedback (MF) connector.
•
Check TS+ and COM wiring.
•
Operate within (not above) the
continuous torque rating for the
ambient temperature.
•
Lower ambient temperature or
increase motor cooling.
•
Verify that the proper motor has
been selected.
F 07
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 that exceeds the
continuous rating of the motor.
Change the command profile to reduce
speed or increase time.
F 10
Inverter Overcurrent
The drive fault output indicates that the power
transistors were turned off because of
overcurrent, overtemperature, or power supply
problems.
Motor cables that are shorted.
Verify continuity of motor power cable
and connector.
Motor winding shorted internally.
Disconnect motor power cables from the
motor. Use multimeter to check that the
resistance of phase-to-phase is not open
and that phase-to-ground is open.
The drive temperature is too high.
• Check for clogged vents or defective
fan.
•
Make sure that cooling is not
restricted by insufficient space
around the unit.
•
Verify that ambient temperature is
within the specification. See Kinetix
350 Drive Power Specifications in
Kinetix Servo Drives Specifications
Technical Data,
publication
.
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 perform 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.
Loss of TTL signal
Check AM+, AM -, BM +, and BM-
signals.
