3.2.1. Single Axis Laser Firing
Single axis firing requires no additional encoder signals and is capable of tracking the
axis position at up to a 20 MHz. tracking rate (50 nsec. minimum edge separation). It
may be programmed to fire from any available encoder source, see Table 3-9. Single axis
firing provides one feature not present with the multi-axes firing option, it allows for
directional based firing. This means that you may program a firing distances for the
positive and negative motion separately. Single axis window firing and Capture/Update
modes may be used with single-axis firing, limited only by the use of the Windows
internal shared queue's.
See Figure 3-6 for a basic single-axis block diagram of the PSO capabilities or Figure 3-4
and Figure 3-5
for a more detailed block diagram of the multi-axis capabilities that also
apply to single-axis firing.
