4.1 Analog signal processing
Function block Function From library
L_SdDelayComp
Extrapolation
• The FB extrapolates a signal by the time set.
LenzeServoDrive
V01.00.xx.xx
L_SdProcessController Comprehensive PID controller with setpoint and ac-
tual value processing as well as parameterisable cha-
racteristic function and limitation
LenzeServoDrive
V02.05.xx.xx
L_Tb8Select 1-out-of-8 selector (for data type "DINT")
• The FB connects one of eight input signals th-
rough to the output.
LenzeToolbox V01.00.xx.xx
L_Tb8SelectByte 1-out-of-8 selector (for data type "BYTE")
• The FB connects one of eight input signals th-
rough to the output.
LenzeToolbox V02.05.xx.xx
L_Tb8SelectWord 1-out-of-8 selector (for data type "WORD")
• The FB connects one of eight input signals th-
rough to the output.
LenzeToolbox V02.05.xx.xx
L_TbAbs Absolute value generation
• The function block converts a bipolar signal to a
unipolar signal, i.e. the absolute value of the input
signal is generated.
LenzeToolbox V01.00.xx.xx
L_TbCompare Comparison
• The function block compares two signals of the
"DINT" data type and can be used e.g. for imple-
menting a trigger.
LenzeToolbox V01.00.xx.xx
L_TbCompare_n Comparison (scaled)
• The function block compares two scaled signals
and can be used e.g. for implementing a trigger.
LenzeToolbox V01.00.xx.xx
L_TbCurve Characteristic function (scaled)
• The FB produces the corresponding value of the Y
axis for the X axis value with a parameterisable
characteristic function y = f(x).
LenzeToolbox V01.00.xx.xx
L_TbCurveAny Characteristic function
• The FB produces the corresponding value of the Y
axis for the X axis value with a parameterisable
characteristic function y = f(x).
LenzeToolbox V02.06.xx.xx
L_TbDeadband Dead band
• The FB produces a symmetrical dead band around
zero.
LenzeToolbox V01.00.xx.xx
L_TbDeadband_n Dead band (scaled)
• The FB produces a symmetrical dead band (scaled)
around zero.
LenzeToolbox V01.00.xx.xx
L_TbDifferentiate Differentiator with low pass
LenzeToolbox V01.00.xx.xx
L_TbGainLim Gain with limitation
LenzeToolbox V01.00.xx.xx
L_TbLimit Signal limitation (for data type "DINT")
• The FB limits a signal of "DINT" data type to an ad-
justable value range.
LenzeToolbox V01.00.xx.xx
L_TbLimit_n Signal limitation (scaled)
• The FB limits a scaled signal [%] to an adjustable
value range.
