8 111B-63494EN/01 1 -1 OVERVIEWS etup for machining, which includes attaching and detaching aworkpiece to be machined, and moving it to the machining start pointwhile viewing it, is performed with the protection door opened. Thedual Check Safety function provides a means for ensuring a high levelof Safety with the protection door simplest method of ensuring Safety when the protection door isopen is to shut off power to the motor drive circuit by configuring asafety circuit with a Safety relay module.

9 In this case, however, nomovements can be made on a move axis (rotation axis). Moreover,since the power is shut off, some time is required before machiningcan be restarted. This drawback can be corrected by adding a motorspeed detector to ensure Safety . However, the addition of an externaldetector may pose a response problem, and the use of many safetyrelay modules results in a large and complicated power magneticscabinet the dual Check Safety function, two independent CPUs built intothe CNC monitor the speed and position of motors in dual mode.

10 Anerror in speed and position is detected at high speed, and power to themotor is shut off via two independent paths. Processing and datarelated to Safety is cross-checked by two CPUs. To prevent failuresfrom being built up, a Safety -related hardware and software test mustbe conducted at certain intervals dual Check Safety function need not have an external detectoradded. Instead, only a detector built into a servo motor or spindlemotor is used. This configuration can be implemented only whenthose motors, detectors built into motors, and amplifiers that arespecified by FANUC are used.
