Slide or Rotary Table Movement Abnormal: Troubleshooting Checklist

Slide table and rotary table movement directly affect loading, mold close, part removal, and operator safety. A table alarm may come from obstruction, position confirmation, sensor feedback, fixture interference, lubrication, sequence timing, or unsafe loading workflow.

Quick Answer

Stop automatic operation and identify which table movement step failed: index, slide in, slide out, position confirmation, or station return. Record the station, fixture state, alarm screen, and recent changes before clearing the alarm.

What You May See

• The slide table or rotary table does not reach the expected position.
• The controller waits for a table position or station confirmation signal.
• Movement stops after insert loading, part removal, or fixture adjustment.
• One station or side creates more alarms than the others.
• The issue appears after fixture change, mold change, lubrication work, or operator workflow change.

Likely Cause Areas

• Fixture, insert, part, cable, or tool may obstruct table movement.
• Position sensor or confirmation signal may be missing or unstable.
• Table guide, rotary mechanism, lubrication, or drive condition may need maintenance review.
• Mold clearance or fixture height may interfere with the movement path.
• Operator loading workflow may leave parts or inserts in the wrong position.
• Controller sequence may wait for a safety, clamp, or station condition before movement continues.

Safe Checks Before Adjustment

Stop automatic operation if movement, alarm, guarding, or operator safety is uncertain. Do not place hands in the mold, table, injection, or guarded area while movement is possible. Use photos, controller screenshots, cycle logs, and safe observation before changing several settings.

Diagnosis Path

1. Stop automatic operation and keep the table area clear.
2. Record the alarm screen, station number if available, and movement step.
3. Check visible obstruction, fixture position, insert placement, part removal, and mold clearance under safe stopped conditions.
4. Identify whether the alarm follows one station, one fixture, one operator side, or all table movement.
5. Review recent fixture, mold, lubrication, sensor, or controller setting changes.
6. Ask qualified personnel to inspect sensors, position confirmation, guide condition, and drive response.
7. Compare table movement alarms with insert shift, loading delay, or part removal issues.
8. Contact support if the alarm repeats or movement position cannot be confirmed safely.

Evidence to Collect

Check	Why It Matters	Evidence to Collect
Station and step	Shows whether the issue is station-specific or general	Alarm screenshot and station note
Fixture and obstruction check	Objects in the movement path can stop the table	Safe stopped photos
Position confirmation	Missing signals often stop the sequence	I/O screenshot or sensor notes if available
Workflow observation	Loading and removal steps can create table interference	Safe video and operator notes
Maintenance history	Lubrication and guide condition affect repeatability	Maintenance and lubrication records

What Not to Change Too Quickly

• Do not reach into the table path while movement is possible.
• Do not bypass station confirmation or safety devices.
• Do not clear repeated alarms without identifying the station and step.
• Do not ignore table alarms that appear with insert shift or part removal problems.

When to Contact Deboge

Contact Deboge when table movement alarms repeat, follow one station, or connect to insert loading or part removal. Send alarm screenshots, table type, fixture photos, station notes, machine model, and safe video if available.
