Fault codes that are triggered by conditions that fall outside factory-set limits are identified by FL at
TIP
the end of the display message. For example, FLT S07 – MTR OVERLOAD FL.
Fault codes that are triggered by conditions that fall outside user-set limits are identified by UL at the
end of the display message. For example, FLT S08 – MTR OVERLOAD UL.
Problem
Motor speed has exceeded 125% of its maximum
speed.
The output frequency has exceeded 590 Hz.
Motor speed has exceeded motor overspeed user
limit.
Calculations based on the motor thermistor indicate
that the motor factory temperature limit has been
exceeded.
The nn sub-code is defined as follows:
01: Motor Thermostat or Thermistor
02: Encoder Temperature Sensor
The motor thermal model has exceeded its factory set
thermal capacity limit of 110%.
The motor thermal model has exceeded the thermal
capacity limit given by Motor Thermal Overload User
Limit.
Torque Prove function detected motor current below a
limit set by Torque Prove Current Limit.
Inverter current has exceeded the instantaneous
current limit (determined by hardware).

Description
Standard runtime axis exceptions.
Manufacturer-specific runtime axis exception.
Exceptions that prevent normal operation and occur during the initialization process.
Exceptions that can prevent normal operation of the drive module and apply to the
entire module.
Exceptions that can prevent normal operation of the drive module, but do not result in
any action other than reporting the alarm to the controller.
Conditions that prevent normal operation and indicate that the drive module is
prevented from being enabled.
An underlying exception condition that does not result in any action other than
reporting the alarm to the controller.
Exception that is generated by a fault condition that is detected in the safety function.

Possible Solutions
Check control loop tuning.
• Check control loop tuning
• Reduce the velocity command
• Check control loop tuning
• Increase the Motor Overspeed UL attribute value
Not supported on induction motors.
• Operate motor within continuous torque rating
• Reduce motor ambient temperature
• Add motor cooling
Available only on Kinetix VP and MP-Series motors. Not supported on
induction motors.
Modify the command profile to reduce speed or increase time.
• Modify the command profile
• Increase the Motor Thermal Overload UL attribute value
Check motor connections.
• Check motor power cable for shorts
• Verify motor windings are not shorted
• Verify motor power wire gauge
• Operate within the continuous power rating
• Modify the command profile to reduce speed or increase time
