Default Connections
General Description
This function can be used only in NE1A-series Controllers with unit version
1.0 or later.
The Pulse Generator function block generates an ON/OFF pulse output at the
Output Enable signal while the function block’s Input signal is ON.
The pulse’s ON time and OFF time can be set independently between 10 ms
and 3 s, in 10-ms increments. When the ON time is set to 100 ms and the
OFF time is set to 500 ms, the signal will repeatedly be turned ON for 100 ms
and then OFF for 500 ms.
Note The output pulse width will have an error equivalent to the cycle time. For
example, if the cycle time is 7 ms and the pulse width is set to 100 ms, the
output pulse will be from 93 to 107 ms.
Set Parameters
The timer SV must be longer than the NE1A-series Controller’s cycle time.
