Product Description
The DMC-18x6 PCI bus motor controllers belong to
Galil’s latest generation motion controller family:the
Accelera Series.Incorporating a 32-bit RISC-based
microcomputer,these controllers offer high-speed
performance and processing power.Speed improve-
ments include acceptance of encoder inputs up to
22 MHz,servo update rates as low as 31 microsec-
onds/axis,and command execution times as low
as 40 microseconds.While the DMC-18x6 offers
performance enhancements compared to prior
gener
ation PCI controllers,the programming lan-
guage and 100-pin SCSI
connector are virtually the
same,making conversion
to the DMC-18x6 quick
and easy.
The DMC-18x6 is avail-
able in one through eight-
axis formats,and each axis is
user-configurable for step-
per or servo motor opera-
tion.The controller includes optically isolated inputs
including a forward limit, reverse limit and home input
for each axis,in addition to uncommitted analog and
digital I/O.Up to two encoders are accepted for each
servo axis.
Standard programming features include PID
compensation with velocity and acceleration feedfor-
ward,multitasking for simultaneously running up to
eight programs,and I/O processing commands for
synchronizing motion with external events.Modes of
motion include point-to-point positioning,position
tracking,jogging,linear and circular interpolation,
contouring,PVT,electronic gearing and ECAM.Like all
Galil controllers,the DMC-18x6 controllers use Galil’s
popular,intuitive command language which makes
them very easy to program.The new GalilTools soft-
ware further simplifies system set-up with “one-but-
ton”servo tuning and real-time display of position and
velocity information.
