Error Codes

Error, fault and alarm codes of products - what each code means, its causes and what to do - read from the manufacturers’ manuals, with the manual page each answer comes from.

• CodeABB ACS550-01 / ACS550-U1 Error 3018: COMM FAULT FUNC

  Communication Fault Function defines the drive’s behavior when fieldbus communication is lost, including coast-to-stop or constant speed mode responses. The manual's first action is: “0 = NOT SEL – No response. 1 = FA…

• CodeABB ACS550-01 / ACS550-U1 Error 3017: EARTH FAULT

  Earth Fault detection is enabled to monitor for ground faults in motor or cable wiring, with configurable response options. The manual's first action is: “See also parameter 3028 WIRING FAULT and 3023 EARTH FAULT LVL.…

• CodeABB ACS550-01 / ACS550-U1 Error 3012: STALL TIME

  The Stall Time parameter sets how long the drive must remain in a stalled condition before triggering a fault response. The manual lists no action for this code.

• CodeABB ACS550-01 / ACS550-U1 Error 3011: STALL FREQUENCY

  This parameter defines the frequency threshold at which the stall protection function activates. The manual's first action is: “Refer to the figure.”

• CodeABB ACS550-01 / ACS550-U1 Error 3010: STALL FUNCTION

  The Stall function is enabled to detect prolonged stall conditions and trigger a fault response based on the time set by parameter 3012. The manual's first action is: “This protection is active if the drive operates i…

• CodeABB ACS550-01 / ACS550-U1 Error 3005: MOT THERM PROT

  Motor overheating protection activates when the calculated motor temperature exceeds 90 °C, triggering an alarm or fault condition. The manual's first action is: “0 = NOT SEL – No response and/or motor thermal protect…

• CodeABB ACS550-01 / ACS550-U1 Error 3004: EXTERNAL FAULT 2

  External Fault 2 is an input signal that triggers a specific response from the drive when detected. The manual's first action is: “See parameter 3003 above.”

• CodeABB ACS550-01 / ACS550-U1 Error 3003: EXTERNAL FAULT 1

  EXTERNAL FAULT 1 defines how the drive reacts to an external fault signal, with options for disabling or using digital input D11 as the trigger source. The manual's first action is: “0 = NOT SEL – External fault signa…

• CodeABB ACS550-01 / ACS550-U1 Error 3002: PANEL COMM ERR

  PANEL COMM ERR specifies the drive’s response to a communication error from the control panel, such as displaying a fault or switching to constant speed mode. The manual's first action is: “1 = FAULT – Displays a faul…
