FB_ParkAxis
The function block FB_ParkAxis enables the parking functionality of a supported Beckhoff drive. A parked channel of a drive is temporarily disabled.
In the case of a modular machine concept, certain motors may not be available. So that this does not lead directly to errors (e.g. feedback errors), the channels can be disabled via this.
Notice | |
Unintentional stopping of axes For multi-channel devices, the controller enables must be switched off for all axes of the corresponding channels before one or more channels are parked. The same applies to activating channels of a multi-channel device. Otherwise, the axes of the other channels may be deactivated unintentionally. |

VAR_IN_OUT
Axis : AXIS_REF;
END_VARName | Type | Description |
|---|---|---|
Axis | Axis data structure that unambiguously addresses an axis in the system. Among other parameters it contains the current axis status, including position, velocity or error state. |
Outputs
VAR_OUTPUT
Busy : BOOL;
Error : BOOL;
