Figure 6.7:"MVS" control bar code for switching between tapes
Use of the "MVS" control bar code for switching between tapes is not dependent on direc-
tion. This means that it functions for switching from tape 1 to tape 2 and vice versa.
Figure 6.8:Switching position with the "MVS" control bar code
If the "MVS" label is passed over, the new tape value is always output relative to the center
of the device or label (see Figure 6.8). In this situation, the hysteresis of ±5mm is irrelevant.
If, however, the device is stopped within the hysteresis on the "MVS" label and the direction
changed, the starting position values have an inaccuracy ±5mm.
