Maximum Stroke

Indramat · ServoDyn D Servo Drive

What does 12 mean?

This error occurs in Automatic mode if the maximum stroke value defined in Parameter 15 (Immediate Stop) is exceeded. This typically happens when Axis 1 travels beyond its allowed stroke limit, often during an Immediate Stop sequence, indicating an overtravel condition.

Common Causes

  • Axis 1 traveling beyond the configured maximum stroke limit set in Parameter 15 (Immediate Stop).
  • Parameter 15 is incorrectly set, allowing a stroke length greater than the physical limit or misinterpreting the required stroke.
  • Axis 1 failing to synchronize correctly with the material speed, leading to unexpected travel distances.
  • Inaccurate position feedback from the encoder for Axis 1, causing the CLM01.3-M to miscalculate the stroke.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Re-evaluate and adjust Parameter 15 (Immediate Stop) to ensure it accurately reflects the physical maximum stroke of Axis 1.

  2. 2

    Verify that Axis 1 is properly synchronizing with the material speed; consult Chapter 6 for detailed instructions on adjusting position lag.

  3. 3

    Check for any mechanical binding, obstructions, or excessive inertia in the system that could cause Axis 1 to overtravel.

  4. 4

    Inspect the Axis 1 encoder for proper operation and verify that its feedback accurately reflects the actual position.

  5. 5

    Review the user program for any commands that might inadvertently cause Axis 1 to exceed its defined stroke limits during operation.
