Danfoss VFD All models error codes
Codes
- 50-58Error codeAutomatic Motor Adaptation failures or drive reset. Alarm 80 means “Drive initialized” (parameters defaulted)
- AL2Error codeAnalog input signal missing or out-of-range. (Occurs if Live Zero Timeout is enabled.)
- AL4Error codeOne phase on the input is missing or unbalanced. Drive will trip if a phase drop persists
- AL7Error codeDrive DC bus voltage is too high (above limit). Often appears as “OVERVOLT”
- AL8Error codeDC bus voltage is too low (below limit). Drive trips
- AL9Error codeDrive is close to overloading. Usually a flashing alarm before trip
- AL10Error codeMotor temperature overload - often amber warning then trip
- AL12Error codeDrive output current hit programmed limit, shows as warning or trip “CURRENT LIMIT”
- AL13LED codePeak current exceeded (trip). The drive’s output surged 200%+. Red LED blinks
- AL14Error codeDrive senses leakage to ground. Occurs when output is shorted to earth/ground
- AL15Error codeNon-compatible option installed
- AL29Error codePower board (heat sink) exceeded safe temp
- AL30Error codeDrive detects an open phase on motor output. This only appears when running (not at start)
