L_Gainoffset_3 - Lenze 8400 StateLine C Reference Manual

16.1.20

L_GainOffset_3

This FB can amplify an analog input signal and then add an offset to it. Preferably to be
interconnected directly after the analog input terminals.
 The internal calculations (addition and subtraction) are carried out with 32 bits without
overflow/underflow. Division is not remainder considered.
 Gain and offset are selected via FB inputs.
 The value provided at the nOut_a output is internally limited to ±199.99 %.
