Description of function
The pulse shape at the output can be modified by a configurable pulse/pause ratio.
|
Connection |
Description |
|
Input En |
You enable/disable the asynchronous pulse generator with the signal at input En. |
|
Input Inv |
The Inv input can be used to invert the output signal of the active asynchronous pulse generator. |
|
Parameter |
T H, T L : You can customize the pulse width (T H) and the interpulse width (T L). |
|
Output Q |
Q is toggled on and off cyclically with the pulse/pause times T H and T L. |
Parameters TH and TL
The pulse width TH and the interpulse width TL can be provided by the actual value of another already-programmed function:
Analog comparator: Ax - Ay
Analog threshold trigger: Ax
Analog amplifier: Ax
Analog multiplexer: AQ
Analog ramp: AQ
Mathematic instruction: AQ
PI controller: AQ
Up/Down counter: Cnt
For the 0BA7 and later version devices, you can additionally use the actual values of the following already-programmed functions:
On-delay: Ta
Off-delay: Ta
On-/off-delay: Ta
Retentive on-delay: Ta
Wiping relay(pulse output): Ta
Edge triggered wiping relay: Ta
Asynchronous pulse generator: Ta
Stairway light switch: Ta
Multiple function switch: Ta
Stopwatch: AQ
Analog filter: AQ
Average value: AQ
Max/Min: AQ
Threshold trigger: Fre
You select the required function by the block number.
Timing diagram
Description of the function
You can set the pulse/pause ratio at the TH (Time High) and TL (Time Low) parameters.
The INV input can be used to invert the output signal. The input block INV only inverts the output signal if the block is enabled with EN.
