RoboteQ MDC1230 Manual

1x80A and
1x120A
Single Channel
Brushed DC Motor
Controller with
Encoder Input,
USB and CAN
Roboteq's MDC1230 and MDC1460 controllers are designed
to convert commands received from an RC radio, Analog
Joystick, wireless modem, PC (via RS232) or microcomputer
into high voltage and high current output for driving one
DC motor. Using CAN bus, up to 127 controllers can be
networked on a single twisted pair. Numerous safety features
are incorporated into the controller to ensure reliable and safe
operation.
The controller features a high-performance 32-bit microcom-
puter and quadrature encoder inputs to perform advanced
motion control algorithms in Open Loop or Close Loop (Speed
or Position) modes. The MDC1xxx features several Analog,
Pulse and Digital I/Os which can be remapped as command or
feedback inputs, limit switches, or many other functions.
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 Basic
Lan guage scripts. The controller can be reprogrammed in the
field with the latest features by downloading new operating
soft ware from Roboteq.
