Free function blocks

6.11.1

Overview

The free function blocks permit configurable signal processing in the inverter.
The following free function blocks are available:
● AND, OR, XOR, and NOT logic
● RSR (RS flip-flop), DSR (D flip-flop) flip-flops
● Timers MFP (pulse generator), PCL (pulse shortening), PDE (ON delay), PDF (OFF
delay), and PST (pulse stretching)
● ADD (adder), SUB (subtractor), MUL (multiplier), DIV (divider), AVA (absolute value
generated), NCM (comparator), and PLI (polyline) arithmetic functions
● LIM (limiter), PT1 (smoothing), INT (integrator), DIF (differentiator) controllers
● NSW (analog) BSW (binary) switches
● LVM limit value monitoring
The number of free function blocks in the inverter is limited. You can only use a function
block once. The inverter has 3 adders, for instance. If you have already configured three
adders, then no other adders are available.
