3.1.4 Position comparison triggering signal output interface

PCI-M324 provides the position comparison triggering pulse output function, as shown in
3
Figure 3.1.4.1. In this example, the encoder feedback value of the servo motor is compared with
the P1 and P2 position set values. When the feedback value equals the P1 or P2 value, the
pulse signal outputs respectively to trigger the image acquisition card or CCD to take images.
The card provides two flexible high-speed comparator channels (Channels #0 and #1) for the
users to choose from. You can choose different pulse comparison sources and pulse output
interfaces according to the parameter settings to meet your application requirements.
