Brushed DC Motor Controller, Triple Channel, 3 x 180A, 60V, Encoder input, USB, CAN, Ethernet

Roboteq's GDC3660 is a feature-packed, very high-current, triple channel controller for brushed DC motors. The controller
features a high-performance 32-bit microcomputer and quadrature encoder inputs to perform advanced motion control algorithms. The motors may be operated in open or closed loop speed mode, position mode or in torque mode.

The GDC3660 features several Analog, Pulse and Digital I/ Os which can be remapped as command or feedback inputs, limit switches, or many other functions. The GDC3660 commands received from an RC radio, Analog Joystick, wireless modem, PLC, or microcomputer. For mobile robot applications, two of the controller's three motor channels can either be operated independently or mixed to move and steer a vehicle. Using CAN bus, up to 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 Basic Language scripts. 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 downloading new operating
