8.4.2 Servo trace
An oscilloscope function is provided for the purpose of optimizing the drives. This enables
graphical representation:
● of the velocity setpoint
● of the contour violation
● of the following error
● of the actual position value
● of the position setpoint
● of exact stop coarse / fine
The start of tracing can be linked to various criteria allowing a synchronous tracing of internal
control states. This setting must be made using the "Select signal" function.
To analyze the result, the following functions are provided:
● Changing and scaling of abscissa and ordinate;
● Measuring of a value using the horizontal or vertical marker;
● Measuring of abscissa and ordinate values as a difference between two marker positions;
● Storing of the result as a file in the part program directory. Thereafter, it is possible to
export the file using either RCS802 or the CF card and to process the data in MS Excel.
Figure 8-18 Servo trace start screen
The header of the diagram contains the current scaling of the abscissa and the difference
value of the markers.
The diagram shown above can be moved within the visible screen area using the cursor
keys.
