8.5 The interval of trigger input
The minimum interval of trigger input is changed based on trigger overlap setting (TriggerOverlap).
The trigger input that does not match minimum interval condition, is invalid.
Please refer “Frame rate” section for “Number of sensor frame line” and “1 H time” in this section.
The minimum interval of trigger input is possible to check with “Frame Trigger Wait” signal through IO port.
When “Frame Trigger Wait” signal is Low status, input trigger signal is invalid.
