Free function blocks
The free function blocks permit configurable signal processing in the inverter.
The following free function blocks are available:
● Logic AND, OR, XOR, NOT
● RSR (RS flip-flop), DSR (D flip-flop)
● Timers MFP (pulse generator), PCL (pulse shortening), PDE (ON delay), PDF (OFF
delay), PST (pulse stretching)
● Arithmetic ADD (adder), SUB (subtractor), MUL (multiplier), DIV (divider), AVA (absolute
value), NCM (comparison), PLI (polygon)
● Closed-loop controllers LIM (limiters), PT1 (smoothing), INT (integrators), DIF
(differentiators)
● Switches BSW (binary) NSW (numeric)
● Monitoring LVM (limit value monitor)
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.
