1 Output phase loss

What does F014 mean?

For the ATV310 drive, this fault is detected when one phase on the drive's output to the motor is lost. This can be caused by poor electrical connections, damaged motor cables, or issues with a downstream contactor.

• Loss of one phase on the drive output terminals (U, V, or W)
• Poor or loose connections from the drive to the motor
• Faulty or damaged motor cable insulation or conductors
• Issue with a downstream contactor, such as an open contact, incorrect connection, or damaged cable

Click steps to track your progress.

1. 1

   Check all power connections between the ATV310 drive output terminals (U, V, W) and the motor terminals for tightness and integrity.

2. 2

   Inspect the motor power cables for any signs of physical damage, nicks, or breaks in insulation.

3. 3

   If a downstream contactor is used, verify its wiring, contact integrity, and proper operation during run conditions.

4. 4

   Measure the voltage at the drive output terminals (phase-to-phase) with the drive enabled to confirm all three phases are present and balanced.
