MC_WriteParameter

The MC_WriteParameter function Block writes the value of an axis-specific non boolean controller parameter. For drive side parameters, refer to Y_WriteDriveParameter.

Parameters

*	Parameter	Data Type	Description	Default
VAR_IN_OUT
B	Axis	AXIS_REF	Logical axis reference.
VAR_INPUT
B	Execute	BOOL	Upon the rising edge of the Execute input, all other inputs are read and the function block becomes operational. If an input needs to be modified, the value will have to be changed and the Execute input will have to be re-triggered.	FALSE
B	ParameterNumber	UINT	Controller parameter number. Refer to parameters with LREAL Data Type in the Axis Parameter List.	UINT#0
B	Value	LREAL	Value of the parameter	FALSE
VAR_OUTPUT
B	Done	BOOL	The Done output is set to TRUE when the commanded action has completed successfully. If another function block takes control before the action is completed, the Done output will never become TRUE. This output is reset when Execute becomes FALSE.
B	Busy	BOOL	For function blocks with Execute input, the Busy output is set to TRUE upon the rising edge of the Execute, and set to FALSE when Done, CommandAborted or Error outputs becomes TRUE. In the case of a function block with an Enable input, Busy indicates that the function block is operating, but may not be ready to provide valid outputs.
B	Error	BOOL	The Error output is set to TRUE if an error has occurred during the operation of the function block. The output is cleared when the Execute or Enable input becomes FALSE.
E	ErrorID	UINT	The ErrorID output provides the identifier of the error when there is an active error in the function block execution. The output is cleared when the Execute or Enable input becomes FALSE.

Notes

Refer to parameters with non BOOL Data Type in the Axis Parameter List.

Example

Instance of MC_WriteParameter writing the value 110.0 to paramater number 1400. In this case, the Default Torque Limit is changed from 100.0 to 110.0.
