Function Generator - Siemens SINAMICS DCM Operating Instructions Manual

Function generator

The function generator is part of the STARTER commissioning tool.
The function generator can be used, for example, to perform the following tasks:
● Measuring and optimizing control loops.
● Comparing the dynamic response of coupled drives.
● Specifying a simple traversing profile without a traversing program.
The function generator can be used to generate various waveforms.
In the "Connector output" operating mode (r4818), the output signal can be injected into the
control loop via the BICO interconnection.
Properties
● The following freely parameterizable waveforms can be set:
– Square-wave
– Staircase
– Triangular
– Sinusoidal
– PRBS (pseudo random binary signal, white noise)
● An offset is possible for each signal. The power-up to the offset can be parameterized.
The signal generation starts after the power-up to the offset.
● Limitation of the output signal to the minimum and maximum value can be set.
Further waveforms
Additional waveforms can be generated.
Example:
The "triangular" waveform can be parameterized with "Upper limit" to produce a triangle with
no peak.
