Installation With Adaptation Characteristic - Siemens SINUMERIK 840C Installation Instructions Manual

If the compensation is acceleration dependant, a characteristic must be determined in a
second stage.
The required compensation amplitudes for differend radii and velocities are determined, the
effect of the compensating amplitudes checked in a circularity test and the optimum
compensation amplitudes logged.
The following characteristic is used for the adaptation:
n
max
n
min
Figure 1
A distinction is made between four ranges in the characteristics:
n =
The characteristics in Figure 1 are used for the following examples. It is defined by the values
"Maximum compensating amplitude", "Minimum compensating amplitude" and the three
acceleration values a
as a control, most importantly there should be a sufficient number of points for high velocities
with small radii. The characteristic values are most easily derived from a graphic
representation.
