 Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Configures the Fast Input The inputs are taken into account at each cycle depending on the system periodicity (i.e., each millisecond). Under certain circumstances, this can be insufficient when more accuracy is needed or if a quick response is required from the system. To fill the gap, a drive may have some Fast Input connections (generally one or two). When an event happens that triggers a Fast Input (e.g., when a sensor sends a rising edge), the detection of a signal occurs faster. This can be 1000 times more accurate than the system periodicity. The timestamp associated with this input can be provided to the IPC to take corrective action. for the axis by writing the expected settings in the Latch The control word is used to activate the drive's latch status machine. The latch control word is processed independently of the EtherCAT® bus cycle. The status word is used to return the drive's latch status. Control Word.

Inputs

Input	Data Type	Range	Unit	Default	Description
En	BOOL	FALSE, TRUE	N/A	No default	Enables Enable signal for the drive, Hardware-Enable with 24V signal to X8, Software-Enable command by setup Software, fieldbus or permanently set. Both are required for enabling the drive. execution.
AxisID	DINT	No range	N/A	No default	ID Name of the Axis block.
InputID	DINT	0, 1	N/A	No default	ID of the FastInput of an axis (e.g., IN1 and IN2 on S300 Servostar 300 drive). InputID INT Range = 0, 1 0 = Touch Probe See Softscope - Probe item. 1 / Capture Engine 0 1 = Touch Probe 2 / Capture Engine 1
Mode	DINT	0, 2	N/A	No default	Configures the Fast Inputs as: 0= Disabled Removal of the ENABLE signal. Disables power stage. 1=Rising edge 2=Falling edge

Outputs

Output	Data Type	Range	Unit	Description
Q	BOOL	FALSE, TRUE	N/A	Returns TRUE when the function successfully executes. Returns FALSE if the fast input could not be configured because of an invalid PDO Process Data Opjects - A type of protocol frame used in some fieldbuses. A PDO contains one or more object dictionary entries, which define the application data transferred between devices. mapping in the .XML Extensible Markup Language - A general-purpose markup language. It is classified as an extensible language because it allows its users to define their own tags. file.

Remarks

Fast Input can be armed on falling or rising edge The transition of a digital signal from low to high. AKA: positive edge..
