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.

• I/O input mapping configuration in the drive (e.g., P7-xx parameters for specific digital or analog inputs) is missing or incorrect.
• PLC/motion controller configuration for the drive's input process image (e.g., mapping of inputs DI1, AI1 to memory addresses) is incorrect or outdated.
• Communication object dictionary mapping for input data (e.g., SDO/PDO settings) is invalid or not properly enabled in the drive.
• Corrupted drive parameter memory impacting the I/O configuration, causing invalid address allocation.
• Firmware bug in the drive preventing correct I/O address allocation in the process image.

Click steps to track your progress.

1. 1

   Access the drive's I/O configuration parameters (e.g., P7-01 for digital input 1, P7-10 for analog input 1) via commissioning software and verify their settings.

2. 2

   Compare the drive's configured I/O input addresses with the PLC/motion controller's expected process image mapping for the drive's inputs.

3. 3

   Perform a re-scan or re-configuration of the drive's I/O modules in the PLC/controller software to regenerate the process image.

4. 4

   Check the communication status of the drive (e.g., using diagnostic LED's or network analysis tools) to ensure a stable connection to the master controller.

5. 5

   Restore the drive's I/O parameter group from a known good backup file and save to non-volatile memory, then power cycle the drive.
