What does FCF2 mean?

Indicates that the output contactor is detected as open when it should be closed. This prevents the drive from supplying power to the motor, resulting in a failure to start or operate. This could be due to a wiring issue, contactor fault, or an active interlock.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Ensure all safety interlocks or permissive conditions for contactor closure are met.

  2. 4

    Measure the voltage supplied to the contactor coil when it should be energized.
