MDI_ReadDriveParameter (FB)

FUNCTION_BLOCK MDI_ReadDriveParameter

This function block can be used to read parameters from the connected ACS or E530 drive product. The parameters from the drive products each belong to a group and have a number within that group. These parameters can be used here to read that value.

InOut:

Scope	Name	Type	Initial	Comment
Input	Execute	BOOL	FALSE	Executes the read of the parameter one time.
	ParGroup	UINT		Allows the user to select the group from which the parameter belongs.
	ParIndex	UINT		Allows the user to select the parameter from the group which will be read.
	ParScaling	REAL	1	Depends on the data type of drive, for example, parameter 46.01 which has two decimal places in drive, this value must be 0.01.
	Timeout	DINT	2000	Read timeout [ms] - Default value is 2000 ms.
Inout	Axis	MDI_AxisRef		Reference to the axis structure.
Output	Done	BOOL		Read completed without an error.
	Error	BOOL		Signals that an error has occurred within function block.
	ErrorID	ERROR_ID		Contains the error code when there is an error.
	Value	REAL		Output value from source parameter (multiplied by ParScaling).
