3.18 Laser Off Mode
Laser off mode is a function to completely stop the laser emission in the measurement region in order to
prevent the interference to the surrounding equipment.
When this mode is enabled, Area1 is automatically assigned for laser off function. During the operation,
UAM will stop the laser emission and switch the OSSD to OFF state whenever the area is switched to Area1.

3.19 Scan Skip Function
Scan skip is a function to stop the laser emission for a specified number of scan cycles in the
measurement region in order to reduce the interference to the surrounding equipment.
When this function is enabled by specifying the skip count, UAM will operate by skipping the scan for
the number of cycles. During the skipping cycle the laser is switched off in the measurement region.
Configurable value for skip cycle is 0 ~ 3 count. Response time of UAM for the different settings is shown
in Table 3-7.
Figure 3-29 shows the operating concept when the scan skip is 0. In this configuration the scan skip
function is disabled and sensor operates normally.
Figure 3-29 Operation of UAM when scan skip count is 0
Figure 3-30 shows the operating concept when the scan skip is set to 2. In this configuration UAM will
skip the measurement for every 2 cycles in between the normal measurement cycles. Outputs states just
before the skipping cycle are retained during the skipping cycle.

Configured active area count in master and slave units should be the same except when using the
encoder input function.
