DMC-1000 ISA Bus Controller
61
The DMC-1000 Series are high-per-
formance, state-of-the-art motion con-
trol cards that install directly into the
ISA bus. Using a 32-bit specialized
microprocessor and a custom gate
array, the controller provides DSP
performance without sacrificing ease
of use and cost effectiveness.
The DMC-1000 is available with 1,
2, 3, or 4 axes per card, and up to 8
axes of control are available with an
attachment card. The DMC-1000 can
also be used with step motors, servo
motors, and hydraulics on any combi-
nation of axes.
The DMC-1000 achieves superior
precision through use of a 16-bit
motor command output DAC and a
sophisticated PID filter that features
Kp, Ki, Kd, and velocity and accelera-
tion feedforward and integration limits.
Advances in speed include 8 mil-
Description
lion counts/sec encoder feedback, a
125 µsec sample rate per axis, and bi-
directional FIFO for high-speed bus
communications with PC interrupts.
Designed to solve complex motion
problems, the DMC-1000 can be used
for applications involving jogging,
point-to-point positioning, vector posi-
tioning, electronic gearing, multiple
move sequences, and contouring. The
controller eliminates jerk by program-
mable acceleration and deceleration
with profile smoothing. For smooth
following of complex contours, the
DMC-1000 provides continuous vec-
tor feed of an infinite number of linear
and arc segments.
For synchronization with outside
events, the DMC-1000 provides
uncommitted I/O, including 8
optoisolated digital inputs, 8 digital
outputs, and 7 analog inputs for inter-
