Abs. Range 2

Hva betyr 26 ?

This error occurs if Axis 2 travels beyond the maximum number of turns (revolutions) supported by its absolute encoder. This indicates an overtravel condition relative to the encoder's multi-turn counting capability, preventing accurate position tracking.

• Axis 2 mechanically travels beyond the physical multi-turn range that the absolute encoder can track.
• Encoder Data A2 parameter (P41) is configured incorrectly for the absolute encoder's actual number of turns.
• Programmed travel limits for Axis 2 (e.g., Parameters 51/52) are set too wide, allowing overtravel.
• Mechanical binding or issues causing unexpected travel that exceeds the encoder's range.

1. 1

   Verify that Parameter P41 (Encoder Data A2) for Axis 2 accurately reflects the total number of revolutions of the absolute encoder.

2. 2

   Adjust the programmed travel limits (e.g., Parameters 51 and 52 for Axis 2) to ensure they are within the absolute encoder's operational range.

3. 3

   Inspect the mechanical system of Axis 2 for any overtravel, binding, or obstructions that would cause it to exceed the encoder's limits.

4. 4

   If a discrepancy exists, compare the value stored in Parameter P41 with the information on the absolute encoder's nameplate.

5. 5

   Review the application's motion profile to ensure that commanded movements for Axis 2 remain within the safe operating range of the absolute encoder.
