Status of the hibernation mode
Parameter Description
r2273 Display of the setpoint/actual value deviation of the technology controller
r2397 Actual hibernation mode output speed
Actual boost speed before the pulses are inhibited or the actual start speed after restart.
r2399 Hibernation mode status word
00 Hibernation mode enabled (p2398 <> 0)
01 Hibernation mode active
02 Hibernation mode delay time active
03 Hibernation mode boost active

Free function blocks

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.

Example
You can find an example for using the free function blocks in Chapter Interconnecting signals
in the converter (Page 447).
