Limiting velocity of regulation (P-AXIS-00220) equal zero expected for spindles without sensor.
Description | Parameter getriebe[i].vb_regelgrenze (P-AXIS-00220) describes the limiting speed above which the measuring system delivers invalid values (e.g. spindles at high speeds). When this speed is exceeded, the position controller of the axis is switched to open-loop controlled operation mode, since without current values the axis cannot be regulated any longer. For a sensor-less spindle, the limiting speed must be set to zero (nil).

Response | Class | 1 | Warning and correction of parameter P-AXIS-00220
Solution | Class | 1 | Spindle without encoder: Set the limiting speed P-AXIS-00220 to zero. Spindle with encoder: Actual values must be included in the cyclic telegram for this axis.
