Output Contactor Open

Hva betyr FCF2 ?

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.

• The output contactor fails to close when commanded.
• Insufficient voltage or current to energize the contactor coil.
• Mechanical obstruction preventing the contactor from engaging.
• Faulty control signal (e.g., from P2-10) commanding the contactor to close.

1. 1

   Verify control wiring to the output contactor coil for continuity and correct voltage.

2. 2

   Check the output contactor for mechanical damage, an open coil circuit, or burnt contacts.

3. 3

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

4. 4

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