WARNING
Reduced resolution during beam blanking may result in serious injury!
 Take the reduced resolution into account when calculating the safety distance (see chapter 6.1.1
„Calculation of safety distance S“).
The “Fixed blanking” function can be combined with the “Floating blanking” function (see
chapter 4.7.2) and the “Reduced resolution” function (see chapter 4.7.4) (see chapter 7.5
„Operating mode 3“).
