3.2.35 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

coupling

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%.
