• Autotune readings that are significantly inconsistent with the configuration
information.
• A non-3-phase motor is being used.
• Incorrect settings at F400 or F413.
• Using a motor that has a significantly smaller rating than the ASD.
• ASD output cabling is too small, too long, or is being housed in a cable tray
with other cables that are producing an interfering EMF.
• Motor is running during the Autotune function.
• F402 adjustment required (Motor temperature is too high).
• F410 adjustment required (Motor Constant 1 improperly set).
• F412 adjustment required (Motor Constant 3 improperly set).
• Autotune setting F400 is set to Auto Calculation and there is a problem with
the Motor Constant readings.
• Firmware information (typeform) loaded into the Gate Driver board is
inconsistent with the device in which the firmware is being used.
• The Gate Driver board has been replaced.
• The Gate Driver board is defective.
• No active faults.
• Improper V/f setting.
• Restart from a momentary power outage.
• The ASD is starting into a rotating motor.
• ASD/Motor not properly matched.
• Phase-to-phase short (U, V, or W).
• Accel time too short.
• Voltage Boost setting is too high.
• Motor/machine jammed.
• Mechanical brake engaged while the ASD is running.
• ASD current exceeds 340% of the rated FLA on ASDs that are 100 HP or
less during acceleration. On ASDs that are greater than 100 HP, this fault
occurs when the ASD current exceeds 320% of the rated FLA during
acceleration.
• Cooling fan inoperative.
• Ventilation openings are obstructed.
• Internal thermistor is disconnected.
• Acceleration time is too short.
• Improper V/f setting.
• ASD or the motor is improperly matched to the application.
