12. DETECTORS FOR THE SPINDLE
B–65162E/03
546
NOTE
– Use the BZ sensor at temperatures not exceeding 80°C.
– The BZ sensor is a precision device. It must be handled with care. In particular, ensure that
no force is applied to the S section.
– The sensor is an electronic device. Provide dust and drip protection on the machine so that
the sensor is not exposed to chips, oil, water, or any other harmful substance.
– Those dimensions that are marked with an asterisk (*) are the dimensions of the sensor
mounting ring. Design a socket and spigot joint on the machine side to match the dimensions.
If a socket joint on the machine side is designed incorrectly, an incorrect signal may be output.
– The gap between the sensor and detection ring is adjusted beforehand. However, an output
signal may not satisfy the specified value due to a socket and spigot joint error. Check the
output signals when mounting a sensor. If an output signal does not satisfy a specified value,
adjust the gap. For information about the output signal level for gap adjustment, refer to Part
II of ”FANUC Built–in AC Spindle Motor α Series Descriptions (B–65202EN).”
– Make a shielded wire connection.
– To ensure ease of maintenance, install a sensor in a location where it can be replaced easily.
– The detection ring of a sensor can be exchanged with another sensor provided the sensors
have the same drawing number.
– A sensor and detection ring cannot be combined if the detection ring is designed for a drawing
number different from that of the sensor.
– A mating connector (accessory) is provided with the BZ sensor.
