Roboteq has unveiled an intelligent controller that can drive a brushed DC motor directly up to 50V and up to 120 amps. The LDC1450 has been designed for being adopted by designers of industrial automation systems, animatronics, automated guided vehicles, mobile robots, or any other motor control application of high power.
By recognizing commands from standard R/C radio, analog joystick, or RS232 interface, the controller can automatically change from one mode to the other.
The LDC1450 has a built-in Basic Language Interpreter that can execute more than 15,000 Basic instructions per second. Using this function, powerful scripts can be effectively and independently written for developing automated systems or adding custom functions. The motor allows operation in open or closed loop speed or position modes having 200 Hz update rate. The LDC1450 features an input for a Quadrature Encoder for measuring traveled distance and speed.
The intelligent current sensing feature of LDC1450 will control the power output automatically in all load conditions. The controller features protection against short circuits, overheat, and stall. The controller has 6 digital, 6 analog, and 6 pulse inputs. Two incorporated 1A digital outputs activate lights, brakes, valves, or other accessories. Around 80 configurable parameters like operating voltage range, programmable acceleration or deceleration, use of I/O, amps limits, etc allows optimization of controller’s function.
A free PC utility is being offered for configuration and operation of the motor. Using the latest features, the controller can be reprogrammed.
The LDC1450 has been designed as a compact 4.45”W x 5.50”L x 1.20"H (113mm x 140mm x 30mm) enclosed design. The controller's conduction bottom plate provides sufficient heat dissipation and does not need a fan during operation.
With cables and PC-based configuration software, the LDC1450 is now being offered to customers.
