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.
