Calculation of the characteristic parameters
The commissioning engineer must determine the optimum values for amplitude, action time,
and decay time for the velocity setpoint pulse for different acceleration values during the
circularity test (Page 334). On completion of the circularity test, the control will calculate the
resulting characteristic parameters (maximum values, characteristic interpolation points, and
weighting factors) and write them into the corresponding machine data.
