NTA FANUC Test 2 – Teach Pendant, Alarms, Jogging And Initial Setup Practice Test

Releasing the DEADMAN switch will cause a controller fault that must be reset before robot motion can be initiated.

False It depends on safety configuration Must be reset after fault True

Correct Answer:

True

Explanation:

Releasing the Deadman switch creates a safety fault in the controller by signaling that the operator is no longer actively controlling the robot. The safety logic immediately stops motion and records a fault state to prevent any unintended movement. To clear this condition and allow motion again, a reset (and any required fault acknowledgment) is needed. After the reset, you’ll typically re-establish control—often by re-engaging the safety features and then enabling jog/run—before the robot can move again. This behavior is by design to ensure the operator is present and attentive before resuming operation.
