Error in the range of the encoder.

Hva betyr 162 ?

The traversing range of the absolute encoder has been exceeded. This means the physical travel of the drive has gone beyond the measurement capabilities of the installed encoder.

• Physical travel of the mechanical system has exceeded the maximum measurement range of the installed absolute encoder (e.g., single-turn limits, multi-turn beyond specified turns).
• Incorrect encoder scaling factor (e.g., Parameter C0301 for pulses per revolution, C0302 for gear ratio) causing misinterpretation of the actual physical position.
• Homing procedure established an incorrect zero point, leading to a calculated position outside the encoder's valid range during normal operation.
• Encoder damage or internal fault causing it to report values outside its specified operational range.
• System mechanics have physically moved beyond the intended safe travel, often due to an unrelated control error or collision.

1. 1

   1. Verify the specified absolute encoder range (e.g., number of turns for multi-turn) and compare it against the actual mechanical travel of the axis.

2. 2

   2. Review and correct the encoder scaling parameters (e.g., C0301, C0302) to ensure accurate position calculation.

3. 3

   3. Re-perform the homing sequence to establish a correct zero position within the encoder's valid operating range.

4. 4

   4. Monitor the actual encoder raw counts (if available in diagnostics, e.g., P5-07) and physical position to pinpoint where the range is exceeded.

5. 5

   5. Check the encoder coupling for slippage or damage that could lead to misreporting of actual position relative to the motor shaft.
