Wire break detection

What does E.ECT mean?

The inverter output is stopped if the encoder signal is lost or turned off. This typically occurs during orientation, PLG feedback, or vector control when executed with the FR-A5AP, indicating a break or interruption in the encoder signal wire.

• A break detected in a sensor wiring harness or communication line.
• Loose connection causing an open circuit in a critical signal path.
• Damage to the wire insulation leading to a physical break.
• Faulty sensor itself reporting an open circuit.

Click steps to track your progress.

1. 1

   Check the encoder signal wires for continuity from the encoder to the FR-A5AP unit.

2. 2

   Inspect the encoder cable and connectors for any signs of damage, loose connections, or improper seating.

3. 3

   Verify the encoder is receiving proper power and generating signals, using an oscilloscope if available.
