I am currently working on a Fanuc robot project involving an extended axis in group one. However, I’ve encountered a critical issue that requires urgent attention.
- The extended axis, which is mounted on a ballscrew and gearbox, behaves unexpectedly when jogged to a specific position (±400mm).
- robot stops only at 400 + - position we checked cables and basic inspection we reconfigured axis we also remastered the axis still no luck
- At this position, the axis stops abruptly, and the robot pendant freezes.
- After a power cycle, the alarm history shows a “hand broke” alarm.
- Interestingly, when I opened the same backup in Roboguide, I noticed that the axis has a stroke limit of 400mm, even though we configured it for 1000mm during initial setup.
- The gear ratio appears to be correct, as the axis travels as expected within its limits.
- Could you please guide me on diagnosing this issue? What steps should I take to identify the root cause?
- Is there a way to override the gear ratio effect on the stroke limit in Roboguide?
- Are there any specific checks or tests I should perform to ensure smooth axis movement?
