Note: The event that caused the trip(s) must be corrected or must decrease to less than the threshold value
required to cause the trip to allow for a Reset to be recognized. In the event of multiple active trips, the
trip displayed will remain until all faults are corrected and cleared.

Possible Cause
• Improper low-current detection level setting.
• Motor (phase) is disconnected.
• Discrete input terminal is configured for
operation and the input activation voltage
level is out of specification.
• Autotune readings are inconsistent with the
configuration information.
• Non-3-phase motor is being used.
• Improper settings at F400 or F410 – 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.
• Improper setting at F412.
• Improper setting at F405, F406, or F407.
• Improper setting at F410.
• Stop-Reset was pressed twice at the EOI.
• E-Off command was received remotely.
• Select stopped method at F603.
• Encoder signal is not received.
• Defective gate array or gate array
malfunction.
• Service call is required.
• Mis-wired ground.
• Loose ground connection.
