Possible Causes

 

 

 

 

 

 

 

 

ETN

 

Autotune readings that are significantly inconsistent with the configuration

 

Autotune Error

 

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

 

Firmware information (typeform) loaded into the Gate Driver board is

 

Typeform Error

 

inconsistent with the device in which the firmware is being used.

 

 

• The Gate Driver board has been replaced.

 

 

• The Gate Driver board is defective.

 

 

 

 

None

No Errors

No active faults.

 

 

 

 

OC1

 

Improper V/f setting.

 

Overcurrent During

• Restart from a momentary power outage.

 

Acceleration

 

 

 

 

 

• 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

 

Cooling fan inoperative.

 

Overheat During

• Ventilation openings are obstructed.

 

Acceleration

 

 

 

 

 

• Internal thermistor is disconnected.

 

 

• Acceleration time is too short.

 

 

Improper V/f setting.

 

 

• ASD or the motor is improperly matched to the application.
