3.2.55 Fixed setpoints (FIXSET)
Purpose
This FB serves to program up to 15 fixed setpoints which can be retrieved via digital terminals or
control codes.
The fixed setpoints can e.g. be used for:
l different setpoint dancer positions for one dancer position control or
l
different stretching ratios (gearbox factor) for a speed ratio control with digital frequency

Function
The FB output can be used as a setpoint source (signal source) for another FB (e.g. process controller,
arithmetic block etc.). Parameter setting and handling are similar to JOG but independent of JOG (cp.
FB NSET).
l
Parameter setting of the fixed setpoints:
– The single fixed setpoints are parameterised via the subcodes of C0560.
l
Output of the fixed setpoint selected:
– If the binary inputs are triggered with HIGH signal, a fixed setpoint from the table is switched
to the output.
l Value range:
– The values for the fixed setpoint can be set between −200% and +200%.
