Table 12. Fault Codes (Continued)
Fault Description Possible Cause
• Optional device malfunction.
• Improper system settings (at ASD or optional
device).
• Loose or improper connection.
• Service call required.
• Over temperature condition detected by option
board.
• Mis-wired output phase.
• Loose output phase connection.
• ASD is starting into a rotating motor.
• ASD/Motor improperly matched to the application.
• Phase-to-phase short (U/T1, V/T2, or W/T3).
• Acceleration time is too short.
• Voltage Boost setting is too high.
• Motor/machine jammed.
• Mechanical brake engaged while the ASD is
running.
• Short Circuit Detection adjustment required
(F613).
• ASD current exceeds 320% or 340% of the rated
FLA on ASDs that are greater than 100 HP or that
are 100 HP or less, respectively, during
acceleration.
• V/f setting needs to be adjusted.
• Restart from a momentary power outage.
• The ASD is starting into a rotating motor.
• ASD/Motor is improperly matched to the
application.
• Phase-to-phase short (U/T1, V/T2, or W/T3).
• Acceleration time is too short.
• Voltage Boost setting is too high.
• Motor/machine jammed.
• Mechanical brake engaged while the ASD is
running.
• ASD current exceeds 320% or 340% of the rated
FLA on ASDs that are greater than 100 HP or that
are 100 HP or less, respectively, during
acceleration.
