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.

Scope of this technical record

ACS510 / ACS550 page depth for OVERCURRENT / 2310 start and acceleration routing, with field-to-bench evidence routing and repair-request qualification.

Safety boundary

This record is for qualified industrial-drive personnel. Isolate the drive, verify stored DC energy is discharged and follow the manufacturer manual before measuring inside the converter or touching motor, brake, field or control wiring.

Service decision coverage

2310 users need a timing split that separates motor/cable/load evidence from output bridge or current-feedback repair.

What this page is meant to decide

This page deepens the ABB ACS510 / ACS550 standard-drive route for OVERCURRENT / 2310 start and acceleration routing. The useful service answer is not a one-line definition; it is whether the event starts on the input energy path, output motor path, terminal command path, ageing-maintenance path or internal electronics boundary.

The page is written for field evidence capture first. That means a technician should be able to collect the type code, fault text, trip timing, wiring photos and maintenance observations before the case is escalated to board repair or whole-drive replacement.

ABB standard-drive service split

ACS510 and ACS550 cases often arrive with a panel message but without the conditions that make the message meaningful. A power-up undervoltage, a run-command overcurrent and a reset request after a cleared fault all require different evidence.

The route therefore separates four layers: line-side supply and DC link, motor/output path, control-terminal command source, and wear or environment evidence. Treating all ABB standard-drive faults as board failure creates false positives and can make a replacement drive fail for the same external reason.

Service route

A 2310 event is split by timing. Instant trips point toward output isolation and static evidence. Ramp trips point toward load, acceleration time and motor data. Load-only trips point toward mechanical or process conditions. Repeated trips after module work require gate-driver and current-feedback evidence.

The page intentionally avoids unsupported component prescriptions. It defines the evidence that decides whether the next step is parameter correction, wiring repair, motor/cable work, maintenance replacement, board-level diagnosis or full drive replacement.

Diagnostic workflow

Evidence intake

Turn this record into a qualified service request

A repair decision is much more reliable when the request includes the exact identity of the drive, the first fault evidence and the machine condition when the symptom appeared.

  • Complete drive type code / MLFB or nameplate model
  • Fault code, fault value and first event before reset
  • When the event appears: power-up, enable, ramp, run, decel or stop
  • Motor/cable connected or isolated during the symptom
  • Visible board, option-card, module and connector identifiers
  • Previous repair history, replacement parts and repeat-failure pattern
