3.4.2.1

Operating area for Period Jitter S

jit1

referring to Table 6. The operating location is defined by air gap and displacement in Y direction. Therefore the

project specific encoder wheel parameters have to be characterized.

In most cases the areas marked in figure Figure 13 are at low air gaps, close to the pole wheel.

The sequence to find the areas marked in Figure 13 is:

•

The encoder wheel magnetic field shall be characterised (measurement of B

•

– If the answer is NO: no further action required

– If the answer is YES: For low jitter S
