ABB ACS580 fault 3210: DC link overvoltage
The drive’s intermediate-circuit (DC link) voltage rose too high and the drive tripped. This usually happens when the motor regenerates energy while slowing down, or when the supply voltage itself is too high.

When it happens
- During deceleration or stopping, especially with high-inertia loads
- With an overhauling load that drives the motor
- At any time if the supply has static or transient overvoltage
Likely causes and checks
1Overvoltage control switched off
- Points to it
- Trips on stops; 30.30 is disabled.
- Check
- Check that 30.30 Overvoltage control is on. ABB notes it must be disabled when a brake chopper and resistor or a regenerative supply is fitted.
2Deceleration too fast
- Points to it
- Trips only on fast stops or large speed reductions.
- Check
- Check the deceleration time; use coast-to-stop where the application allows.
3Brake chopper or resistor not working, or wrongly sized
- Points to it
- A resistor is fitted but trips continue.
- Check
- Check the brake chopper and resistor, and that the resistor is dimensioned correctly with resistance within the allowed range.
4Supply voltage too high
- Points to it
- Trips even on gentle stops or at standstill.
- Check
- Check that the supply voltage matches the drive’s nominal input and look for static or transient overvoltage on the supply.
Telling it apart
- Trips on deceleration point to regenerated energy (ramp, overvoltage control, braking); trips while running steadily or stopped point to the supply.
- If the process needs fast stops of a heavy load, ABB’s listed fix is a brake chopper and resistor.
Relevant parameters
| Parameter | Name | Why it matters |
|---|---|---|
| 30.30 | Overvoltage control | Reduces braking torque to hold the DC voltage down; disable when a brake chopper and resistor or a regenerative supply is used. |
| 23.xx | Deceleration times | Longer deceleration returns energy more slowly. |
| 31.12 | Autoreset selection (bit 1: overvoltage) | Can reset overvoltage automatically; only once the cause is understood. |
Evidence to collect
- Event log entry for 3210 and what the drive was doing
- Deceleration time and stop mode
- Setting of 30.30
- Whether a brake chopper and resistor are fitted, and the resistor value
- Measured supply voltage
