Description

Enable

BOOL

Value range: FALSE, TRUE.

Default value: FALSE.

The input Enable starts or terminates execution of a function block.

FALSE: Execution of the function block is terminated. The outputs Valid, Busy, and Error are set to FALSE.
TRUE: The function block is being executed. The function block continues executing as long as the input Enable is set to TRUE.

Output	Data type	Description
Valid	BOOL	Value range: FALSE, TRUE. Default value: FALSE. FALSE: Execution has not been started or an error has been detected. The values at the outputs are not valid. TRUE: Execution has been completed without an error detected. The values at the outputs are valid and can be further processed.
Busy	BOOL	Value range: FALSE, TRUE. Default value: FALSE. FALSE: Function block is not being executed. TRUE: Function block is being executed.
Error	BOOL	Value range: FALSE, TRUE. Default value: FALSE. FALSE: Execution of the function block is running, no error has been detected. TRUE: An error has been detected in the execution of the function block.
ErrorID	WORD	Returns the value of a diagnostic code. Refer to Library Diagnostic Codes. If the value is 0 and if the output Error of this function block is set to TRUE, then the diagnostic code can be read with the output AxisErrorID of the function block MC_ReadAxisError.
AxisErrorID	WORD	Initial value: 0 This output shows library-specific and drive-specific error codes. Refer to the chapter Library Diagnostic Codes for a list of the library-specific error codes. Refer to the drive documentation for an overview of the drive-specific error codes.

Input/Output	Data type	Description
Axis	Axis_Ref	Reference to the axis (instance) for which the function block is to be executed (corresponds to the name of the axis). The name of the axis must be defined in the EcoStruxure Machine Expert Devices tree.
