PCL-832
3-axis Servo Motor Control Card
Features
• Independent 3-axis servo control
• 3-axis linear interpolation
• 2-axis circular interpolation
• 1 msec. servo update time
• Easy programming from C and other high-level languages
• Six axes maximum in one PC system
• Half-size AT (ISA bus) add-on card
• 12-bit analog output with ±10 V range
• Built-in F/V converter
Introduction
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
implement position control. Each axis has its own position control
chip, allowing complete independent control of up to three servo
motors.
A special synchronization circuit synchronizes all three axes
simultaneously. 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.
The PCL-832's programming library (accessible from 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
interpolation, circular interpolation, return home
and jog.
