3. The Maximum Frame Rate (Shortest Trigger Cycle)
A. During Continuous Operation (Frame Start trigger is ”Off”)
FR_Cont[Hz] = MIN( Interface_FR , Sensor_FR_TRIG_OFF )
B. When TriggerMode is ”On” (Frame Start trigger is ”On”)
1. First, calculate the maximum OverlapTime value for the shortest trigger cycle.
[GOX-6409MC-PGE]
MaxOverlapTime_TrOlrd[us] = (1000000/ FR_Cont ) - (V_Sync_TrigOn[H] -
ExposureProhibitPeriod[H]) x H_Period[us]
[GOX-12409MC-PGE/GOX-20409MC-PGE]
MaxOverlapTime_TrOlrd[us] = (V_Sync_TrigOn[H] - ExposureProhibitPeriod[H]) x H_Period[us]
Please refer to the table below for V_Sync_TrigOn and ExposureProhibitPeriod.

2. Finally, calculate the maximum frame rate.
a) When ExposureTime ≦ MaxOverlapTime_TrOlrd
FR_TrOlrd[Hz] = MIN( Interface_FR , Sensor_FR_TRIG_ON )
b) When ExposureTime > MaxOverlapTime_TrOlrd
Non-OverlapExposureTime_TrOlrd = ExposureTime - MaxOverlapTime_TrOlrd
[GOX-6409MC-PGE]
Under this scenario, the FR_TrOlrd value is applicable because the larger the ExposureTime
is, the lower the Sensor_FR_TRIG_ON value becomes. Use the formula described in ” a)
When ExposureTime ≦ MaxOverlapTime_TrOlrd .”
[GOX-12409MC-PGE/GOX-20409MC-PGE]
FR_TrOlrd_w_NonOlExp[Hz] = 1000000÷{ (1000000/ FR_TrOlrd ) +
Non-OverlapExposureTime_TrOlrd }
