2.2.12 Limiting (L_LIM)
This FB limits signals to preset ranges of values. You can fix the range of values by defining an upper
and a lower limit.
L _ L I M
n O u t _ a n I n _ a
n M a x L i m i t
n M i n L i m i t

VariableName DataType SignalType VariableType Note
nIn_a Integer analog/velocity VAR_INPUT
nOut_a Integer analog/velocity VAR_OUTPUT
nMaxLimit Integer VAR CONSTANT RETAIN Defines the upper limit. (100 % º 16384)
nMinLimit Integer VAR CONSTANT RETAIN Defines the lower limit. (100 % º 16384)

VariableName L_LIM1 SettingRange Lenze
nMaxLimit C0630 −199.99 ... 199.99 % 100.00
nMinLimit C0631 −199.99 ... 199.99 % −100.00
Note!
The lower limit must always be set lower than the upper limit.
Otherwise nOut_a is set = 0.
