A20B-8100-0190 Fanuc Loader Control Dual Check Safety

The dual check safety function need not have an external detector added. Instead, only a detector built into a servo motor or spindle motor is used. This configuration can be implemented only when those motors, detectors built into motors, and amplifiers that are specified by FANUC are used. When an abnormality related to safety occurs, the dual check safety function stops operation safely.The dual check safety function ensures safety with the power turned on, so that an operator can open the protection door to work without turning off the power. A major feature of the dual check safety function is a very short time required from the detection of an abnormality until the power is shut off. A cost advantage of the dual check safety function is that external detectors and safety relays can be eliminated or simplified. A20B-8100-0190
