ERR9
Flash Memory Fault
• Flash memory malfunction.
• Make a service call.
ETN
Autotune Error
•
No motor connected or improperly secured connection.
•
Autotune
readings that are significantly inconsistent with the configuration
information.
• A non-3-phase motor is being used.
• Incorrect settings at
F400
,
F413
, or
F616
.
• 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
• F402
adjustment required (Motor temperature is too high).
•
F412
adjustment required (Motor Constant 3 improperly set).
• Motor shaft is rotating during
Autotune
.

ETYP
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.
None
No Errors
• 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.
