RGDC18xx Motor Controller Datasheet 1
RGDC18xx
Roboteq’s RGDC18xx is a very high current, feature-packed
motor controller for Brushed DC motors. The controller fea-
tures a high-performance 32-bit microcomputer and several
quadrature encoder inputs to operate in open or closed loop
speed mode, position mode or in torque mode. The RGDC18xx
features several Analog, Digital and Pulse I/Os which can be
remapped as command or feedback inputs, limit switches, or
many other functions.
The RGDC18xx accepts commands received from an RC radio,
Analog potentiometer, wireless modem, PLC, or microcom-
puter. Using CAN bus, as many as 127 controllers can be
networked at up to 1Mbit/s on a single twisted pair. Numerous
safety features are incorporated into the controller to ensure
reliable and safe operation.
The controller’s operation can be extensively automated and
customized using a built-in simple programming language. The
controller can be configured, monitored and tuned in real-time
using a Roboteq’s free PC utility. The controller can also be
reprogrammed in the field with the latest features by down-
loading new operating software from Roboteq.
