ACS510 / ACS550 standard drive platform

A practical model-family record for ACS510 and ACS550 standard drives, oriented around nameplate identification, keypad evidence, external terminal wiring and the first diagnostic boundary for undervoltage, line-converter and overcurrent symptoms.

Record facts

Primary useStandard VFD control for pumps, fans and general machinery
Common evidenceKeypad fault text, parameter/fault history, terminal wiring and nameplate option code
Service boundaryInput/DC link, control terminal I/O, motor/output path and maintenance wear items
Database roleBridge from general VFD triage into ABB-specific ACS510/ACS550 pages

Service notes

  • Record the full type code, input voltage, output current and option codes before comparing symptoms.
  • Do not treat DC UNDERVOLT, LINE CONV and OVERCURRENT as one generic failure; each points to a different first diagnostic boundary.
  • Control-terminal miswiring can mimic a drive fault when start, direction, reference or external fault commands are interpreted incorrectly.
  • Routine evidence such as fan condition, dust, terminal tightness and capacitor appearance matters for old ACS510/ACS550 installations.

Related technical records

3220 / DC UNDERVOLT
Intermediate DC Circuit Undervoltage

The drive trips on DC UNDERVOLT / 3220, may not become ready, or may trip when load or line conditions pull the DC link below the permitted level.

Open →ff51 / LINE CONV
Line Converter Fault Indication

The drive reports LINE CONV / ff51 or points the technician toward the input/line-converter side rather than the motor output side.

Open →2310 / OVERCURRENT
Output Overcurrent During Start or Acceleration

The ACS510/ACS550 trips on OVERCURRENT / 2310 when a start command is issued, during acceleration, or under a sudden load condition.
