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 %  16384)

nMinLimit Integer VAR CONSTANT RETAIN Defines the lower limit. (100 %  16384)

Parameter codes of the instances

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.
