Deceleration.
Over-Current During Fixed
Speed Operation.
Possible Cause
• 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 is jammed.
• Mechanical brake is 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.
• Phase-to phase short (U/T1, V/T2, or W/T3).
• Deceleration time is too short.
• Motor/machine is jammed.
• Mechanical brake is 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.
• ASD/Motor is improperly matched to the
application.
• Load fluctuations.
• ASD is operating at an elevated temperature.
• 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.
