ABB · ACS850 Standard Program Firmware
This fault occurs when the amount of data being sent by the system exceeds the maximum capacity of an ICM (Industrial Communication Module) telegram. This typically happens in host applications using doMultipleCommands with too many encapsulated calls, preventing proper data transmission and potentially causing communication timeouts.
Click steps to track your progress.
1. Reduce the number of parameters or data points configured for cyclic transmission within the ICM telegram.
2. Divide the large data block into smaller chunks that fit within the maximum ICM telegram payload size.
3. Review the ICM module's configuration to ensure its telegram structure is optimized for the data being exchanged.
4. Check the documentation for the specific ICM module and drive for maximum supported telegram sizes.
5. Update the firmware of the ICM module or the drive if there are known issues with telegram handling or size limits.
6. Utilize alternative communication methods or multiple telegrams if a single telegram cannot accommodate the required data.
