2. Expand the Trigger panel by clicking on the panel header.
3. Select the trigger source from the drop-down.
4. Configure the settings.
See the trigger parameters above for more information.
5. Save the job in the Toolbar by clicking the Save button .
Maximum Input Trigger Rate
The maximum external input trigger rate in a system including Master 400 or higher is 20 kHz.
When using a standalone sensor or a sensor connected to a Master 100, the maximum trigger rate is 32
kHz. This rate is limited by the fall time of the signal, which depends on the Vin and duty cycles. To
achieve the maximum trigger rate, the Vin and duty cycles must be adjusted as follows:
Maximum Speed Vin Maximum Duty Cycle
32 kHz 3.3 V 88%
32 kHz 5 V 56%
32 kHz 7 V 44%
32 kHz 10 V 34%
At 50% duty cycle, the maximum trigger rates are as follows:
Vin Maximum Speed
3.3 V 34 kHz
5 V 34 kHz
10 V 22 kHz
Maximum Encoder Rate
On a standalone sensor, with the encoder directly wired into the I/O port or through a Master 100, the
maximum encoder rate is about 1 MHz.
For sensors connected through a Master 400 or higher, with the encoder signal supplied to the Master,
the maximum rate is about 300 kHz.
Sensor
The following sections describe the settings that are configured in the Sensor panel on the Scan page.
Active Area
Active area refers to the region within the sensor's maximum field of view that is used for laser profiling.
By default, the active area covers the sensor's entire field of view. By reducing the active area, the sensor
can operate at higher speeds.
