⚠️ Quick Fix for ABB Error 20401
If this error appears, try these immediate actions:
Quick checks often restore safe robot operation.
ABB Robot Error 20401 – Safety System Triggered occurs when the ABB IRC5 Controller detects activation of a safety input, such as an emergency stop, safety gate, or safety PLC signal. This alarm is designed to prevent unsafe operation of the robot.
Error 20401 indicates that the robot has received a safety input signal causing it to stop operation immediately. All robot movements are suspended until the safety system is cleared.
Affected areas may include:
Manually pressed or accidentally activated E-Stop buttons trigger the safety system and stop robot motion.
Common issues include:
Regular inspection and maintenance prevent unnecessary stops and ensure operator safety.
Open or misaligned safety gates and interlock switches can activate the safety system, halting robot operation.
Common issues include:
Routine checks and proper alignment of safety gates/interlocks maintain continuous safe operation.
Defective switches, relays, or wiring can cause false safety triggers.
Entering a restricted SafeMove zone or violating a configured safety zone can trigger the alarm.
Incorrect safety system configuration or outdated firmware can produce false alarms.
Replacement is recommended if:
Persistent safety system errors may require hardware replacement or configuration support:
