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. - Write 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 to reset 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.
