Sensing Head Mounting Requirements
The Sensing Head must be mounted relative to the Detecting Gear as
shown in Figure 4. For proper operation, it is critical that the center line of
the gears be positioned as shown relative to the mounting surface of the
sensor. The air gap between the Detecting Gear surface and the surface of
the circular sensing plate on the Sensing Head must be 0.15
±
0.05 mm. A
properly designed mounting support will permit sufficient adjustment to
assure proper alignment and will be rigid enough to prevent sensor
movement relative to the gear.
Sensing Head Wiring To 8510 AC Spindle Drive
Refer to Chapter 8 in the 8510 AC Spindle Drive System User Manual
(publication 8510-5.1) for wiring details.
