FB_ParkAxis

The function block 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.

Supported Beckhoff hardware
AX5xxx	AX8xxx / MD8xxx	Compact drive technology
from FW v2.12 b0001	from FW v1.06 b0003

Inputs

VAR_INPUT
    Execute : BOOL;
    Mode    : E_ParkMode;
END_VAR

Inputs/outputs

VAR_IN_OUT
   Axis : AXIS_REF;
END_VAR

Name	Type	Description
Axis	AXIS_REF	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;
    ErrorID : UDINT;
END_VAR

Name	Type	Description
Busy	BOOL	This output is set when the function block is activated, and remains set until a feedback is received.
Error	BOOL	This output is set after the Busy output has been reset when an error occurs in the transmission of the command.
ErrorID	UDINT	In the event of a set error output returns the ADS error code.
