ABB ACS580 Fault 2310 Meaning
ABB ACS580 fault 2310 is an output overcurrent trip. The drive measured current high enough to protect the inverter output stage, motor, and connected load.
Treat 2310 as a fault to diagnose before ordering parts. A bad motor cable, weak motor insulation, wrong motor data, or a locked pump or fan can destroy a replacement drive if you install hardware before isolating the cause.
Common Causes
- Shorted motor lead or damaged cable shield.
- Motor winding insulation breakdown.
- Ground fault close to the drive output.
- Pump, fan, conveyor, blower, or gearbox locked under load.
- Acceleration time too short for the load inertia.
- Motor nominal current, voltage, frequency, or control mode entered wrong.
- Output contactor changing state while the ACS580 is enabled.
- ACS580 output stage damage after external faults are ruled out.
ACS580 2310 Checks {#acs580-2310-checks}
- Read the ACS580 fault logger before clearing the fault. Record the fault code, auxiliary value, motor current, speed, and whether 2310 occurred at startup, acceleration, constant speed, or deceleration.
- Lock out power and wait for the DC bus to discharge. Follow the ACS580 hardware manual and site electrical procedures before touching drive terminals.
- Inspect the U/V/W output wiring. Look for loose terminals, crushed cable tray sections, oil-soaked cable, shield strands near power lugs, or heat marks.
- Disconnect the motor leads and test the motor and cable with a rated insulation resistance tester. Compare phase-to-ground and phase-to-phase results before reconnecting.
- Rotate or uncouple the driven load when the process allows it. A stuck pump, blocked fan, jammed conveyor, or seized bearing can trigger 2310 even when the motor tests clean.
- Compare the motor nameplate to the ACS580 motor data. Pay close attention to nominal current, voltage, frequency, motor type, and control mode.
- Increase acceleration time and retest under controlled conditions. If the fault clears with a longer ramp, the original ramp was too aggressive for the load.
- If 2310 returns with the motor disconnected, stop and treat the ACS580 output stage or current-sensing hardware as suspect.
What the Fault Timing Means
| When 2310 appears | Most likely focus |
|---|---|
| Immediately on enable | Output short, connected contactor issue, hardware |
| During acceleration | Ramp too short, motor data, locked load |
| At constant speed | Mechanical load spike, cable fault, loose output |
| During deceleration | Load instability, control tuning, regen context |
| With motor disconnected | Drive output stage or current-sensing fault |
Parts and Tools
Use parts searches after the first electrical checks point to a component. For most 2310 trips, the right order is motor/cable test, load inspection, motor-parameter review, ramp adjustment, then ACS580 hardware evaluation.
If you need a replacement drive, match the complete ACS580 catalog number, voltage, current rating, enclosure rating, brake option, EMC option, and communication adapter before ordering.
