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.

Important Warning Carefully follow the wiring instructions provided in the Power Connection section of the User Manual. The information on this datasheet is only a summary. Mandatory Connections It is imperative that the controller is connected as shown Figure 2, above, in order to ensure a safe and trouble-free operation. All connections shown as thick black lines line are mandatory. The controller must be powered On/Off using switch SW1on the Power Control input.
