FF0206h

External Encoder Implausible Values

SEW Eurodrive · MOVI-PLC SyncCrane Application

What does FF0206h mean?

This fault indicates that the external encoder is providing implausible position or feedback values to the MOVI-PLC® system. This can be caused by issues such as wire breakage in draw-wire encoders. Upon detection, the axis system is automatically stopped if operating in automatic mode.

Common Causes

  • External encoder is sending illogical or inconsistent position data.
  • Encoder signal is intermittent or corrupted.
  • Faulty external encoder hardware.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Inspect the wiring of the external encoder to the MOVI-PLC® encoder input terminals.

  2. 2

    Measure encoder supply voltage at the terminal block.

  3. 3

    Check encoder signal integrity by observing raw encoder counts or signal waveforms (if possible).

  4. 4

    Verify encoder resolution and type settings in the MOVI-PLC® parameters match the physical encoder.
