17 Function library
17.1 Function blocks
This chapter describes the function blocks which are available for the inverter in the FB Editor.
Overview of function blocks available
The system blocks are described in the chapter "System blocks". ( 1529)
Note!
From version 06.00.00, a maximum of 65 function blocks instead of 50 can be used in the
function block interconnection. The computing power remains unchanged, i.e. the max.
computing time is approx. 300 μs.
