LS_PulseGenerator

This system block outputs 9 different fixed frequencies and 1 frequency with parameterisable

pulse/dead time.
The SB provides a TRUE signal at the bFirstCycleDone output when the first 1-ms processing cycle is

completed and the time set in 1

C00400/3

has expired. This status signal can e.g. be used for the

delayed enable of peripheral devices or motor control setpoints so that all required initial values are

calculated first after the controller switch-on.
