Optimize The Drive - Siemens SINUMERIK 840D sl Commissioning Manual

Optimize the drive.

You can optimize the drives in the "Commissioning" > "Optimization/Test" operating area.
The following functions are available:
● Frequency response measurements for the following control loops:
● Automatic controller setting
● Function generator
● Circularity test
● Servo trace
Measuring functions
The measuring functions make it possible to assess the automatic controller action of the
respective control loop (frequency response) by the integrated FFT analysis (Fast Fourier
Transformation) without external measuring equipment.
The measurement results are represented graphically as a Bode diagram. HMI file functions
can be used to archive the diagrams for documentation purposes and to simplify remote
diagnostics.
Circularity test
The circularity test serves to set and assess the dynamic response for interpolating axes or
to analyze the contour accuracy on the quadrant transitions (circular contours) achieved by
means of friction compensation (conventional or neural quadrant error compensation).

Servo trace
The servo trace provides a graphically assisted analysis of the time response of position
controller and drive data.
