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

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