    3.2 Isolated Input Ports (LTC, INCOM) There are 4 pairs of isolated input ports on PCI-8124. Each pair has two terminals. One is INCOMx, and the other is LTCx. Because the input port of the photo coupler utilized on PCI-8124 is single-directional, LTC signal must be lower than INCOM signal.

  • Page 36 Inside the PCI-8124, all the position comparison and mapping tasks will be executed within the FPGA. The functional block is as follows: The FIFO will automatically load the comparing points into 32-bit comparator. The comparator will compare the data from counter and FIFO individually.

  • Page 37: Encoder Channel

    4.1.1 Encoder Channel The PCI-8124 has four 32-bit binary up/down counters to keep the present feedback position from each encoder channel. The counter counts signal inputs from the EA and EB pins. The counter source could be assigned to internal timer.
  • Page 38 Dual Pulse Mode (CW/CCW Mode) In this mode, EA is dedicated to count the pulses from external source and view it as clockwise direction (CW). EB is dedicated to count the pulses from external source and view it as counterclock- wise direction (CCW).

  • Page 39: Index Input (Ez)

    90° phase shifted signals (AB phase Mode) In this mode, EA signal is a 90° phase leading or lagging to EB signal. “Lead” or “lag” of phase difference between two signals is caused by the turning direction of the motor. The up/down counters counts up when the phase of EA signal leads the phase of EB signal.

  • Page 40: Homing With Ez Signal

    4.1.3 Homing with EZ Signal The PCI-8124 can clear the counter value as zero according to the edge of EZ signal. Homing by edge can let users meet best hom- ing positioning purpose. Rising or falling edge is supported. The following diagram shows the case about the homing by rising edge.

  • Page 41: Fifo

    4.1.6 FIFO FIFO is first-in-first-out storage. It is used for storing some preset position data for comparing. Every time the position is compared, a new data is retrieve from FIFO into comparator. This mechanism makes a the continuous triggering function. 4.1.7 PWM &...

    Example: Using the continuous position comparison function. In this application, the table is controlled by the motion command, and the CCD Camera is controlled by the position comparison out- put of the PCI-8124. An image of the moving object is easily obtained. Operation Theory...

  • Page 43: Position Latch

    User’s can read the latch reg- ister any time. 4.2.3 Linear Function There are 10 linear functions in PCI-8124. Each function is inde- pendent. It means that linear function range overlapped is possible when operation. Each linear function has its own comparator and the comparator could be linked to any one of four counters.

  • Page 44: Timer Function

    4.2.5 Timer function There are 4 timers on PCI-8124. The timer is started by TTL input and the timer can be set to counters to simulate encoder inputs. It can also output to trigger pins directly. The timer is designed by a down-counter.

  • Page 45: Multiple Boards Operation

    S1. With this benefit, users can control each board accordingly without any confusion. For example, if three PCI-8124 cards are plugged in to PCI slots, then the corre- sponding channel number on each card will be: CH No.

  • Page 46: Interrupt Control

    4.4 Interrupt Control The PCI-8124 can generate an INT signal to the host PC. Users have to enable the interrupt service with this function call, _8124_set_int_factor. On the contrary, the parameter of intFactor of function is set to 0 to disable the interrupt service.
  • Page 47 Use wait function we provided to wait interrupts under Win- dows To detect an interrupt signal from the PCI-8124 under Windows, we provided an easier way to deal with the interrupt process. The following steps are described that how you use those interrupt functions.
