Warnings and faults
Warning Fault Aux. code Description
A2A1 2281 Current calibration Warning:
Current calibration is done at the next start.
Fault:
Output phase current measurement fault.
- 2310 Overcurrent The output current is more than the internal limit. This can also be caused by
an earth fault or phase loss.
A2B3 2330 Earth leakage A load unbalance that is typically caused by an earth fault in the motor or the
motor cable.
A2B4 2340 Short circuit There is a short-circuit in the motor or the motor cable.
- 3130 Input phase loss The intermediate DC circuit voltage oscillates due to missing input power
line phase.
- 3181 Wiring or earth fault Incorrect input and motor cable connection.
A3A1 3210 DC link overvoltage Intermediate DC circuit voltage is too high.
A3A2 3220 DC link undervoltage Intermediate DC circuit voltage is too low.
- 3381 Output phase loss All three phases are not connected to the motor.
- 5090 STO hardware failure STO hardware diagnostics has detected hardware failure. Contact ABB.
A5A0 5091 Safe torque off The Safe torque off (STO) function is active.
A7CE 6681 EFB comm loss Break in embedded fieldbus communication.
A7C1 7510 FBA A communication Communication lost between drive (or PLC) and fieldbus adapter.
A7AB - Extension I/O
configuration failure
The I/O extension module types and locations specified by parameters do
not match the detected configuration.
AFF6 - Identification run The motor ID run occurs at the next start.
- FA81 Safe torque off 1 loss The Safe torque off circuit 1 is broken.
- FA82 Safe torque off 2 loss The Safe torque off circuit 2 is broken.
