Figure 5.4: Measurement range changeover via MVS control bar code

NOTE

Measurement range changeover!

The measurement range changeover from the preceding to the subsequent BCB occurs
when the center of the BPS 8 (

in Figure 5.4) is opposite the center of the control bar

code (

in Figure 5.4).

NOTE

Hysteresis for measurement range changeover!

If a measurement range changeover occurs in the center of the MVS control bar code to
the subsequent BCB, a hysteresis range of ± 2mm (

in Figure 5.4) is activated.

If the direction of movement is reversed within this hysteresis range, a measurement range
changeover occurs to the preceding BCB 15 mm after the center of the MVS control bar
code.

Within this range of 15 mm, the position values are calculated from the subsequent BCB.
