DMC-18x6 Series

Product Description

nnnn

The DMC-18x6 PCI bus motor controllers belong to

nnnn

Galil's latest generation motion controller family: the

nnnn

Accelera Series. Incorporating a 32-bit RISC-based

nnnn

microcomputer, these controllers offer high-speed

nnnn

performance and processing power. Speed improve-

nnnn

ments include acceptance of encoder inputs up to

nnnn

22 MHz, servo update rates as low as 31 microsec-

nnnn

onds/axis, and command execution times as low

nnnn

as 40 microseconds. While the DMC-18x6 offers

nnnn

DMC-1886 performance enhancements compared to prior

nnnn

and DMC-1846 generation PCI controllers, the programming lan-

nnnn

guage and 100-pin SCSI

nnnn

connector are virtually the

nnnn

same, making conversion

nnnn

tothe DMC-18x6 quick

nnnn

and easy.

nnnn

The DMC-18x6 is avail-

nnnn

able in one through eight-

nnnn

axis formats, and each axis is

nnnn

user-configurable for step-

nnnn

per or servo motor opera-

nnnn

tion.The controller includes optically isolated inputs

nnnn

including a forward limit, reverse limit and home input

nnnn

for each axis, in addition to uncommitted analog and

nnnn

digital I/O. Up to two encoders are accepted for each

nnnn

servo axis.

nnnn

Standard programming features include PID

nnnn

compensation with velocity and acceleration feedfor-

nnnn

ward, multitasking for simultaneously running up to

nnnn

eight programs, and I/O processing commands for

nnnn

synchronizing motion with external events. Modes of

nnnn

motion include point-to-point positioning, position

nnnn

tracking, jogging, linear and circular interpolation,

nnnn

contouring, PVT, electronic gearing and ECAM. Like all

nnnn

Galil controllers,the DMC-18x6 controllers use Gain's

nnnn

popular, intuitive command language which makes

nnnn

them very easy to program.The new GalilTools soft-

nnnn

ware further simplifies system set-up with"one-but-

nnnn

ton" servo tuning and real-time display of position and

nnnn

velocity information.

nnnn

Features

nnnn

■ PCI card in 1 through 8 axis versions:

nnnn

DMC- 18x6 where x= 1,2,3,4,5,6,7,8 axes

nnnn

■ User-configurable for stepper or servo motors on any

nnnn

combination of axes. Optional firmware for piezo-ceramic

nnnn

motors. Configurable for sinusoidal commutation

nnnn

■ Accepts up to 22 MHz encoder frequencies for servos.

nnnn

Outputs up to 6 MHz for steppers

nnnn

■ PID compensation with velocity and acceleration feedfor-

nnnn

ward, integration limits, notch filter and low-pass filter

nnnn

■ Modes of motion include jogging, point-to-point position-

nnnn

ing, contouring, PVT, linear and circular interpolation,

nnnn

electronic gearing and electronic cam. Features elliptical

nnnn

scaling, slow-down around corners, infinite segment feed

nnnn

and feedrate override

nnnn

■ Over 200 English-like commands including conditional

nnnn

statements and event triggers

nnnn

■ Non-volatile memory for programs, variables and arrays.

nnnn

Multitasking for concurrent execution of up to eight

nnnn

programs

nnnn

■ Optically isolated home input and forward and reverse

nnnn

end-of-travel limits accepted for every axis.

nnnn

■ 1- through 4-axis: 8 isolated inputs and 8 outputs

nnnn

5- through 8-axis: 16 isolated inputs, 16 outputs,

nnnn

8 digital inputs

nnnn

■ High speed position latch for each axis and output compare

nnnn

nnnn

■ Dual encoder inputs for each servo axis

nnnn

■ Expansion for 64 I/O with optional DB-14064 board

nnnn

■ 100-pin SCSI connectors for each set of 4 axes. ICM-2900

nnnn

or ICM-1900 breaks-out 100-pin cable into screw terminals

nnnn

■ AMP-19540 connects to PCI controller with 100-pin cable

nnnn

and provides four amplifiers for 500 W servos

nnnn

■ Communication drivers for Windows, Mac OSX, and Linux

nnnn
