Motion step skipped
Bosch Rexroth · IndraDrive MPx02
What does F2003 mean?
This non-fatal error indicates that a programmed motion step in a sequence or profile was skipped by the IndraDrive MPx02. This can lead to unexpected machine behavior, loss of synchronization, or incorrect positioning.
Common Causes
- Incorrect programming of the motion sequence or conditions for step execution.
- Insufficient processing power or communication latency causing the drive to miss a step command.
- Invalid data or unexpected conditions encountered during the execution of a motion block.
- External interlocks or conditions that were not met, preventing the execution of a step.
- Firmware bug or internal logic error in the IndraDrive MPx02.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Review the motion program or sequence to ensure logical flow, correct sequencing, and valid conditions for each step.
- 2
Check the communication cycle time between the master controller and the IndraDrive MPx02 to ensure it is fast enough for the application.
- 3
Verify parameter settings related to motion execution, such as S-0-0145 (Motion sequence buffer size).
- 4
Monitor external interlock signals and their timing to confirm they are not inadvertently causing steps to be skipped.
- 5
Update the IndraDrive MPx02 firmware to the latest version to address potential software issues.
