17.2.29 LS_PulseGenerator
This system block outputs 9 different fixed frequencies and 1 frequency with parameterisable
pulse/dead time.
From version 06.00.00 onwards, the SB provides a TRUE signal at the bFirstCycleDone output when
the first 1-ms processing cycle is completed and the time set in 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 inverter switch-on.
