Product Description

Roboteq’s LDC1430 (30V) / LDC1450 (50V) controller is 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. Designed for maximal ease-of-use, it is delivered with all necessary cables and hardware, and is ready to use in minutes.

The controller features a high-performance 32-bit microcomputer and quadrature encoder inputs to perform advanced motion control algorithms in Open Loop or Close Loop (Speed or Position) modes. The LDC1430/LDC1450 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 Language scripts. The controller can be reprogrammed in the field with the latest features by downloading new operating software from Roboteq.
