230 GX9 ASD Installation and Operation Manual
ETN Autotune Error • 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.
ETN1 • F402 adjustment required (Motor temperature is too high).
• F410 adjustment required (Motor Constant 1 improperly set).
ETN2 • F412 adjustment required (Motor Constant 3 improperly set).
ETN3 • Autotune setting F400 is set to Auto Calculation and there is a problem with
the Motor Constant readings.
ETYP ASD Typeform Error • 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.
NERR No Error • No active faults.
OC1 Over-Current During
Acceleration
• 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.
OC1P Over-Heat 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.
