1.18 Use Cases
1.18.3.1.2 Using Counter
It is also possible to use Counter and CounterEnd as the trigger event for synchronizing images with an incremental
encoder
To create an external trigger event by an incremental encoder, please follow these steps:
1. Connect the incremental encoder output signal A, for example, to the digital input 0 ("Line4") of the mv
BlueCOUGAR-X .
This line counts the forward pulses of the incremental encoder.
2. Set "Setting - Base -
Counter1" and
3. "Counter Event Source" to "Line4" to count the number of pulses e.g. as per revolution (e.g. "Counter
Duration" to 3600).
4. Then set the trigger "Setting -
"FrameStart" to the "Counter1End" ("Trigger Source") signal.
To reset "Counter1" at Zero degrees, you can connect the digital input 1 ("Line5") to the encoder Z signal.
