Address IO input structure

What does 4642 mean?

The drive lacks a valid I/O input address in the process image. This indicates a mapping error where the NC system cannot correctly read input data (e.g., encoder feedback, limit switch status) from the drive because its process image address is either missing or invalid. This will lead to a lack of critical feedback for control.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Check for consistency between the hardware's physical I/O and the software's process image mapping.

2. 4

   Save configuration changes and restart the NC system.
