The self-calibration is operational when the requirements are in accordance with Table 14.

Note

• Values at room temperature

• Recommended screws for the rotor: M2 ISO 4762 (stainless steel A4) with recommended torque = 0.3 Nm ± 10 % + narrow

washer M2 NFE 25514 “Z” type (stainless steel A4) thickness 0.5 mm. It is recommended to add glue on screws threads

function of environmental and use conditions

• Recommended screws for the stator: M1.6 ISO 1207 (stainless steel A4, screw head diameter

≤ 3.2 mm and screw head

height

≤ 1 mm) with recommended torque = 0.10 Nm ± 10 % + washer M1.6 DIN 125 (insulated raw material) thickness

0.3 mm. It is recommended to add glue on screws function of environmental and use conditions

OTHER INFORMATION

ATTENTION!

Observe Precautions for Handling Electrostatic

Sensitive Devices!

Do not use magnetic parts around the encoder!

WARNING: the rotor and the stator must have the same serial number!

• Do not damage the magnetic disk surface

• Do not put the disk in contact with metallic particles

• Do not use cleaning product or chemical product

TABLE 14 - RECOMMENDED DIMENSIONS AND TOLERANCES OF CUSTOMER INTERFACES TO

USE THE SELF-CALIBRATION PROCEDURE

Rep 3

Diameter runout of the customer shaft for the rotor centering

(included gap between customer shaft and inner rotor diameter) (see Fig. 9)

< 0.08 mm

Rep 4

Misalignment: concentricity of the stator centering diameter versus shaft centering diameter

(included tolerances of customer holder and stator interface) (see Fig. 9)

± 0.8 mm

Rep 5

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

(air-gap: the condition of previous line avoids to measure the air-gap)

2.65 mm ± 0.2 mm

(air-gap = 0.5 mm ± 0.2 mm)

Rep 6

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

< 0.2 mm
