SINUMERIK 801
Start-Up
To optimize the drives, an oscillograph function is provided for graphical
representation of the velocity setpoint. The velocity setpoint corresponds to
the ± 10V interface.
The start of recording can be linked with various criteria which permit
recording in parallel to internal conditions of the control system. The setting
needed for this option must be carried out in the "Select Signal" function.
The following functions can be used to analyze the result:
Change scaling of abscissa and ordinate,
Measure value by means of a horizontal or vertical marker,
Measure the abscissa and ordinate values as a difference between two
marker positions.
