Address IO output structure

Was bedeutet 4643 ?

The drive lacks a valid I/O output address in the process image. This means the NC system cannot correctly write output data (e.g., control commands, enable signals) to the drive because its process image address is either missing or invalid. This prevents the drive from receiving commands and acting upon them.

• I/O output mapping configuration in the drive (e.g., P8-xx parameters for specific digital or analog outputs) is missing or incorrect.
• PLC/motion controller configuration for the drive's output process image (e.g., mapping of outputs DO1, AO1 to memory addresses) is incorrect or outdated.
• Communication object dictionary mapping for output 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.

1. 1

   Access the drive's I/O configuration parameters (e.g., P8-01 for digital output 1, P8-10 for analog output 1) via commissioning software and verify their settings.

2. 2

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

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.
