PCL-833 User Manual 2
1.1 Introduction
The PCL-833 is a 3-axis quadrature encoder and counter add-on card for the KM PC/
AT and compatibles (ISA bus). This card lets your PC perform position monitoring for
motion control systems. It provides three 24-bit up/down counters as quadrature
encoders and a 16-MHz oscillator time base with wide-range multiplier. An on-board
interrupt controller handles nine different interrupt sources.
Encoder interface
Each input includes a decoding circuit for incremental quadrature encoding. Inputs
accept either single-ended or differential signals. Quadrature input works with or
without an index, allowing linear or rotary encoder feedback.
Counters
The PCL-833 has three independent 24-bit counters. The maximum quadrature input
rate is 1.0 MHz, while the maximum input rate in counter mode is 2.4 MHz. You can
individually configure each counter for quadrature decoding, pulse/direction counting
or up/down counting.
Digital input and interrupts
The PCL-833 provides five digital input channels. The channels accept digital input
as an index input for a rotary encoder or as a home sensor input for a linear encoder.
The card can generate an interrupt to the system based on a signal from its digital
inputs, overflow/underflow of its counters or on a programmed time interval. It can
repeatedly generate interrupts at anytime interval you specify, 0.I mini sec to 255
sec. These interrupts let you precisely monitor the speed of a control system.
