A2/W2 - Live Zero Error fault in danfoss drive

Cause: The analog input signal is below 50% of the set minimum value for the specified terminal. This typically occurs in a 4-20mA control loop where the signal has been lost.
Solution:
  • Verify that the control signal wiring to the analog input terminal is correct and secure.
  • Check the source of the analog signal (e.g., PLC, sensor) to ensure it is functioning correctly and providing the expected signal range.
  • If the input board is suspected to be faulty, consider replacing the I/O or control PCB.
