Ethernet /RS232 Econo 1 8 axes
Product Description
Galil`s DMC-21x2 and DMC-21x3 Ethernet motion
controllers are designed for extremely cost-sensitive
and space-sensitive applications.These intelligent, card-
level controllers are available with a variety of plug-in
multi-axis amplifier boards that are designed to elimi-
nate the wiring and any connectivity issues between
the controller and drives.
The DMC-21x2 and DMC-21x3 are similar except
the DMC-21x2 controllers use a 100-pin high-density
SCSI connector and the DMC-21x3 controllers use a
96-pin DIN connector.
The controllers incorporate a 32-bit microcomputer
and provide such advanced features as PID compensa-
tion with velocity and acceleration feedforward, pro-
gram memory with multitasking for simultaneously
running up to eight programs, and uncommitted I/O
for synchronizing motion with external events. Modes
of motion include point-to-point positioning, jogging,
linear and circular interpolation, contouring, electronic
gearing and ECAM.
Like all Galil controllers, these controllers use a sim-
ple, English-like command language which makes them
very easy to program.Galil`s WSDK servo design software
further simplifies system set-up with "one-button"servo
tuning and real-time display of position and velocity
information.Communication drivers are available for
DOS, Linux and all current Windows operating systems.
Features

PID compensation with velocity and acceleration feedfor-
ward, integration limits, notch filter and low-pass filter
Modes of motion include jogging, point-to-point position-
ing, contouring, linear and circular interpolation, electronic
gearing and ECAM. Features ellipse scaling, slow-down
