MC_ReadParameterSet

MC_ReadParameterSet 1:

The complete parameter set of an axis can be read with the function block MC_ReadParameterSet.

	In this case "axis" refers to the TwinCAT NC axis and not the drive.

Inputs


VAR_INPUT
    Execute : BOOL;
END_VAR

Execute

The command is executed with the rising edge.

Outputs


VAR_OUTPUT
    Done    : BOOL;
    Busy    : BOOL;
    Error   : BOOL;
    ErrorID : UDINT;
END_VAR

Done	Becomes TRUE, if the parameters were read successfully.
Busy	The Busy output becomes TRUE when the command is started with Execute and remains TRUE as long as the command is processed. If Busy becomes FALSE again, the function block is ready for a new order. At the same time one of the outputs, Done or Error, is set.
Error	Becomes TRUE if an error occurs.
ErrorID	If the error output is set, this parameter supplies the error number

Inputs/outputs


VAR_IN_OUT
    Parameter : ST_AxisParameterSet;
    Axis      : AXIS_REF;
END_VAR

Parameter	Parameter data structure into which the parameters are read
Axis	Axis data structure

The axis data structure of type AXIS_REF addresses an axis unambiguously within the system. Among other parameters it contains the current axis status, including position, velocity or error state.
