Characteristic
Average rigidity
Standard deviation of
the rigidity
The equability test notifies the machine operator of faults and interference resis-
tances from feed axis elements. The curve of the recorded values indicates at
which axis position the disturbance is located. A trend analysis of the characteris-
tics will indicate any change in the status of the drive train.

Description
For calculating the characteristic, the mean rigidity
value is determined in the measured position range at
the configured speed.
For calculating the characteristic, the standard devia-
tion of the rigidity is determined in the measured posi-
tion range at the configured speed.
