PCI-8372+/PCI-8366+

DSP-based SSCNET II 12/6-axis Motion Control Cards

Serial-connection Multi-Axis Motion Controller

ADLINK PCI-8372+/PCI-8366+ is a 12/6-axis motion control cards

based on PCI bus. The PCI interface provides plug-and-play feature

that is the key to easy maintenance. The maximum number of cards

in one system is up to 12 cards, offering users the following advantages.

Advantages

• Easy-wiring and time-deterministic

• Command synchronization

• Easy-maintenance

• Maximum motor speed can be achieved under maximum motor

resolution (17-bit)

• 32-bit command resolution

• Connecting distance up to 30 meters

• Parameter setting and tuning by software

• Absolute encoder control (ABS position) control

Motion Control Principle

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

on PCI-8372+/PCI-8366+. 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 PCI-

8372+/66+ 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

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 DI, 2 open collector output DO are included to provide

general purpose I/O.

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 outputs

These are two modes for analog: Direct 16 bits +/-10 volts output,

velocity command monitoring.

Hardware Synchronization

The PCI-8372+/PCI-8366+ can be synchronized via the CN4 connector

between every card.

Servo Amplifier/Motor Support

ADLINK PCI-8372+/PCI-8366+ is designed for *SSCNET II series

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