cPCI-8312H

Advanced 6U CompactPCI SSCNET II 12-axis Motion Control Card with HSL Network

Serial-Connection Multi-Axis Motion Controller

ADLINK cPCI-8312H is a 12-axis motion control card based on

CompactPCI bus. They contain two main features: SSCNET II motion

control and HSL network control. SSCNET II motion control allows

users to connect Mitsubishi servo motors to realize high performance

and to benefit from absolute synchronization mechanism.

HSL network control also allows users to take advantage of the high-

speed, real-time, and distributed connection while building up the

entire application. These two main features can meet users' requirement

in motion and distributed I/O control simultaneously. The CompactPCI

interface offers plug-and-play feature that is key to easy maintenance.

The maximum number of cards in one system is 12 cards, offering

users the following advantages:

Motion Control Principle

The motion command is accomplished by the host PC and the DSP

on cPCI-8312H. DSP accomplished the synchronization between users'

program control and SSCNET update cycle. Motion profiles are split

into several frames and trans-ferred to the DSP via DPRAM. According

to these frames, DSP calculates the absolute position of all axes in

one control cycle and send each position to the individual driver via

the *SSCNET II at the same cycle. The cPCI-8312H can also collect

data from the servo driver via the SSCNET II at the same cycle including

servo parameter, position, speed, torque etc. The cycle time is 0.888ms

which is defined in *SSCNET II protocol.

Operation Modes

Single axis motion; Linear interpolation; Circular interpolation mode;

mult-axis simulta-neous start motion; contour motion; change

speed/position on-the-fly; and home return modes.

Mechanism Interface

Dedicated limit switch and origin input points for each axis.

General Purpose I/O

2 isolated digital output channels.

Pulse Train Interface

This board offers users 2 pulse train output channels for users to

connect pulse train type servomotors. The maximum frequency is

4.16MHz.

Interrupt Events

The hardware interrupts are transformed into softrware events or

signals. An event driven applications under multi-tasking OS can be

realized by this way.

Analog Inputs and Outputs

These are two modes for analog: Direct +/- 10 volts output with 16-bit

resolution and velocity command monitoring. 2 analog inputs are also

available for this board.

Servo Amplifier/Motor Support

ADLINK cPCI-8312H is designed for SSCNET II series servo

amplifier/motor including MR-J2S-B and MR-J2M-B.
