ABB ACS580 fault 2310: Overcurrent
The drive measured output current above its internal fault limit and tripped. ABB notes that the same fault can also be caused by an earth fault or by a lost supply phase, not only by a genuinely high load current.

When it happens
- At start or during acceleration (ramp too short for the load)
- On a sudden load increase or a jam
- Immediately at start when the motor or its cable is faulty
Likely causes and checks
1Load too heavy or acceleration too fast
- Points to it
- Trips during the ramp; fewer trips with a lighter load or a longer ramp.
- Check
- Check the motor load and the acceleration times in group 23 (speed ramp), 26 (torque) or 28 (frequency).
2Wrong scaling
- Points to it
- Trips after commissioning or a parameter change.
- Check
- Check scaling parameters 46.01, 46.02 and 46.03.
3Motor data wrong
- Points to it
- Drive replaced or motor changed recently.
- Check
- Compare the motor data in group 99 with the motor rating plate.
4Motor, cable or connection fault
- Points to it
- Trips instantly at start, even with little load.
- Check
- Check the motor and motor cable, including phasing and the star/delta connection.
5Equipment switching in the motor cable
- Points to it
- Trips coincide with a contactor operating between drive and motor.
- Check
- Check for contactors opening or closing in the motor cable while the drive runs.
6Capacitors or surge absorbers on the motor side
- Points to it
- Power-factor capacitors or surge absorbers are fitted in the motor cable.
- Check
- Check for and remove power-factor capacitors or surge absorbers from the motor cable.
7Earth fault
- Points to it
- Trips persist with the load removed.
- Check
- Measure the insulation resistance of the motor and cable, with the motor disconnected from the drive.
Telling it apart
- If the trip happens partway through a start, ramp time and load are the first suspects; if it happens the instant the drive starts, look at the motor, cable and connections.
- Because ABB lists an earth fault and a lost supply phase as possible triggers, an insulation test and a check of the supply are worthwhile even when the load looks normal.
Relevant parameters
| Parameter | Name | Why it matters |
|---|---|---|
| 23.xx / 26.xx / 28.xx | Acceleration times (speed, torque, frequency ramps) | Too short a ramp for the load’s inertia is a common trigger. |
| 46.01–46.03 | Speed, frequency and torque scaling | Wrong scaling is listed by ABB as a cause. |
| 99.xx | Motor data | Must match the motor rating plate. |
| 31.12 | Autoreset selection (bit 0: overcurrent) | Can reset overcurrent automatically; only enable once the cause is understood. |
Evidence to collect
- Event log entry for 2310 with its time stamp
- Acceleration time and ramp settings
- Group 99 motor data and the motor rating plate
- Whether a contactor, capacitors or surge absorbers sit in the motor cable
- Insulation test results
