2.1 General signal processing
2.1.1 Programming fixed setpoints (L_FIXSET)
You can program up to 15 fixed setpoints with this FB. The addressing of the setpoint that is to be
output is made through the boolean (logic) inputs.
Fixed setpoints can be used, for example, for:
Different set dancer positions in a dancer position control
Different stretch ratios (gearbox factor) when using a speed ratio control with digital frequency

nAin_a Integer analog VAR_INPUT nAin_a is connected to nOut_a , if (bIn1_b ... bIn4_b)
FALSE is on all the selection inputs.
bIn1_b Bool binary VAR_INPUT
The number of inputs to be assigned depends on the
number of required fixed setpoints.

Function
nOut_a can be used as a setpoint source (signal source) for another FB (e.g. process controller,
arithmetic block, etc.). The parameterization and handling is the same as for JOG, but it is
independent of JOG. (^ 2−73: L_NSET)
Parameterization of the fixed setpoints
– The individual fixed setpoints can be parameterized through anSollW1 ... anSollW15.
Output of the selected fixed setpoint:
– If the binary inputs are triggered with a HIGH signal, a fixed setpoint from the table is
switched to nOut_a . (^ 2−3)
Range:
– You can enter values from −199.99% ... 199.99% (100 % corresponds to 16384).
