Abstract
A computing facility transmits a command to a numerical control to briefly actuate a spindle drive, receives from the numerical control a drive torque applied to the spindle drive and data about a resulting acceleration of the spindle and determines therefrom a moment of inertia of the spindle and the spindle drive. The computing facility retrieves from the converter parameters describing the maximum possible operating limits of the converter and motor data of the drive motor, from which the maximum possible torque of the spindle drive can be determined as a function of the speed of the drive motor. The computing facility receives from an operator process data which include at least the process torque and determines required currents and torques and thermal losses in the spindle drive. The operator selects from the determined combinations, on the basis of which the limit values below a predetermined loss limit are determined.
