Function generator parameter settings

Field Description

Name

SINAMICS Trace:

Parameters

Parameter name of the variable for which the function generator returns the

value.

You can enter this directly, or select it in the"Function generator signal

selection" view. To do so, click "Signal selection" at the end of the field. This

view shows all system variables available for the technology objects.

Syntax for entering the signal name:

You must have created at least one technology object in the project.

You can also output the signals of both function generators to one system

variable. The signals are then superimposed (not with SINAMICS Trace).

FctGen Cycle

(not SINAMICS Trace)

The selected system variable is updated with the function generator signal in

the function generator cycle. Specify the cycle as a multiple of the position

controller cycle.

Note:

To generate a precise reconstruction of the trace shape selected under "Signal

type" by means of the function generator, the function generator cycle must be

significantly shorter that the signal period.

Signal type Here you select cyclic or acyclic signals with a different trace profile, which you

want to generate by means of the function generator.

• Enter the required signal parameters. Which parameters are available

depends on the selected signal type.

Individual trace parameters displayed in red print indicate that the values you

have entered are not valid.
