MOUNTING DATA AND SELF-MONITORING

After the mounting and throughout the use of the sensor, the encoder provides across the LED colors and also across data bits

of self-monitoring the status of correct mounting and of correct operation. Look at section “Self-Monitoring” and the table

“Summary” in section “Approach No. 2”, “Self-Calibration Procedure” of §1.

APPROACH NO. 1: TOTALLY PLUG AND PLAY WITHOUT SELF-CALIBRATION

Comment: it is the case for the customer’s equipment whose mechanical tolerances are under control (requirements described

in Table 13).

TABLE 13 - RECOMMENDED DIMENSIONS AND TOLERANCES OF CUSTOMER INTERFACES

Rep 1

Customer shaft diameter for centering of the rotor (see Fig. 9)

25 mm + 0 mm / - 0.010 mm

Rep 2

Customer interface diameter for centering of the stator (see Fig. 9)

60 mm + 0.060 mm / 0 mm

Rep 3

Diameter runout of the customer shaft for the rotor centering (see Fig. 9)

< 0.005 mm

Rep 4

Concentricity of the stator centering diameter versus shaft centering diameter (see Fig. 9)

< 0.020 mm

Rep 5

Position of the stator reference bottom surface versus rotor reference bottom surface (see Fig. 9)

2.65 mm ± 0.1 mm

Rep 6

Total beat included in the air-gap between Ref. C (rotor) and Ref. D (stator) (see Fig. 10)

< 0.2 mm
