SMC_GetMaxSetAccDec (FB)¶

FUNCTION_BLOCK SMC_GetMaxSetAccDec

This function block may be employed to measure the maximum absolute value of acceleration (or deceleration) of an axis. Measuring will be done if bEnable is TRUE, and will be reset to 0, if bEnable is FALSE. With dwTimeStamp you can provide a call counter, which is latched output in dwTimeAtMax with a new maximum value.

InOut:

Scope	Name	Type	Initial	Comment
Inout	`Axis`	AXIS_REF_SM3
Input	`bEnable`	`BOOL`	FALSE	`TRUE`: Starts execution of function block.
Input	`dwTimeStamp`	`DWORD`		Optional time stamp input; can be used to find out when the maximum has occured.
Output	`bValid`	`BOOL`	FALSE	`TRUE`: Parameter is available.
	`bBusy`	`BOOL`		`TRUE`: Execution of the function block has not been finished.
	`fMaxAcceleration`	`LREAL`	0	Maximum acceleration in [u/s²]
	`dwTimeAtMax`	`DWORD`	0	Maximum value of `dwTimeStamp`
