 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 (for example 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 (which can be 1000 times more accurate than the system periodicity). Then 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	No range	N/A	No default	Enables 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" See Servo Drive in Glossary). InputID INT Range = 0, 1 0 = Touch Probe 1 / Capture Engine 0 1 = Touch Probe 2 / Capture Engine 1
Mode	DINT	0, 2	N/A	No default	Configures the Fast Inputs The inputs are taken into account at each cycle depending on the system periodicity (for example 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 (which can be 1000 times more accurate than the system periodicity). Then the timestamp associated with this input can be provided to the IPC to take corrective action as: 0= Disabled 1=Rising edge 2=Falling edge

Outputs

Output	Data Type	Range	Unit	Description
Q	BOOL	No range	N/A	Returns TRUE when the function successfully executes. Returns FALSE if the fast input The inputs are taken into account at each cycle depending on the system periodicity (for example 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 (which can be 1000 times more accurate than the system periodicity). Then the timestamp associated with this input can be provided to the IPC to take corrective action could not be configured because of an invalid PDO PDO is 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 " XML is 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 A rising edge is the transition of a digital signal from low to high. It is also called positive edge.
