3-axis control
The PCL-832 3-axis Servo-motor Control Card turns your IBM PC or
compatible computer into a sophisticated position controller. The
card's custom ASIC implementation provides high performance at an
affordable price.
The PCL-832 uses digital differential analysis techniques to imple-
ment position control. Each axis has its own position control chip,
allowing completely independent control of up to three servo motors.
A special synchronization circuit synchronizes all three axes. The card
can supply a simulated tachometer output to the servo motor driver.
This signal makes a tachometer unnecessary in some applications,
reducing overall system costs.
Software Drivers
The PCL-832's programming library (accessible from Microsoft C)
supports high-level commands and functions, making control easy.
The library includes commands to set the DDA cycle time and
acceleration/deceleration curve as well as functions for linear interpo-
lation, circular interpolation, return home and jog. Numerous exam-
ples of driving programs have also been included on the utility/
software disk.
