(7)-4 The installation of the sensor head
The installation method of αi BZ sensor is described below.
① Attach the sensor head to the sensor mounting surface so that the groove on the sensor
head is engaged with the parallel pins, and fix the sensor head temporally. Be careful
that the detection ring does not strike the sensor head in installing.
② Put the feeler gage (included: t=0.15mm) between the detection ring and the sensor
head. Push the sensor head to the detection ring lightly and fix the sensor head firmly
(recommended fastening torque: 1.3Nm +/- 10%). Use of some kind of thread locker is
recommended to prevent loosening of the screw to fix the sensor head.
③ Pull off the feeler gage. Rotate the spindle slowly and check that the detection ring does
not contact with the sensor head.
④ Confirm the gap between the sensor head and the detection ring is more than 0.1mm.
⑤ The α
i BZ sensor is so designed that the output voltage of the sensor is within the
permissible amount. But there is a possibility of that the voltage does not satisfies the
specification with the inappropriate installation.
Check that the output voltage satisfies the signal specification described in FANUC
