S-III: incorrect sequence during phase switch
Bosch Rexroth · IndraDrive MPx02
What does F4017 mean?
This fault indicates an incorrect sequence of communication phases during a switch, specifically related to phase S-III operation on the IndraDrive MPx02. This can disrupt the synchronous operation of the drive.
Common Causes
- Master communication device sending an incorrect phase sequence or timing.
- Incorrect configuration of communication parameters in the IndraDrive MPx02 (e.g., S-0-0010, S-0-0011).
- Disturbances or interference on the communication bus during phase switching.
- Software or firmware issues in either the master controller or the IndraDrive MPx02.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Verify the communication master's configuration for phase switching and sequence, ensuring it aligns with the IndraDrive MPx02 requirements.
- 2
Check communication parameters in the IndraDrive MPx02, such as S-0-0010 (Master communication cycle time) and S-0-0011 (Drive communication cycle time), for correct settings.
- 3
Inspect the communication bus cabling (e.g., SERCOS, EtherCAT) for proper termination, shielding, and absence of damage.
- 4
Monitor the communication signals for integrity and noise using appropriate diagnostic tools, if available.
- 5
Update the firmware of the IndraDrive MPx02 to the latest version, if applicable, to address potential known issues.
