Okuma OSP Alarm A 1837 - Worktable overload
Worktable overload
The work table overload sensor activated and the 'Interlock/(Workpiece Push limit switch)' signal turned OFF, meaning the table or pushed workpiece exceeded its load limit. The machine stops to protect the table and workpiece.
Common Causes
- Workpiece pushed too hard against the worktable or stop
- Overload sensor activated by excessive cutting or clamping force
- Workpiece push limit switch misadjusted or faulty
- Mechanical interference driving the table past normal load
Troubleshooting Steps
- 1Inspect the workpiece setup: check how the part is pushed against the table or stop and relieve any excessive pushing force or misalignment.
- 2Examine the workpiece push limit switch and the overload sensor for damage or misadjustment; confirm the switch actuates cleanly when the table is loaded and releases when unloaded.
- 3Follow the manual's measure: reset the alarm and manually move the spindle in the positive Z-axis direction to back the load off the table sensor.
- 4Re-approach the workpiece with reduced force or feed and confirm the overload sensor no longer trips during normal setup and cutting.
