KUKA 1488 (“VACUUM PUMP FAULT”): Vacuum missing or too weak. First check: Check the vacuum pump.

Updated 2026-09-09 · LogrobotLM reference

Cause

Vacuum missing or too weak. The check is performed from a PLC user program (bonding technology). In the "windshield bonding" application, the windshields are held by means of the vacuum control. If this vacuum is not present, the windshield cannot be held in position after centering.

Effect

Stop via braking ramp. All active commands are inhibited.

Troubleshooting

Check the vacuum pump.
