PERFORMANCE CONTROLS, INC.® Digital Motor Drives for Brush Motors DCD48-200

The DCD Series of four-quadrant and two-quadrant DC motor servo drives utilizes a high performance Digital Signal Processor (DSP), high efficiency MOSFETS, and proprietary control techniques to perform smooth, reliable motor control functions with a high degree of flexibility. Parameters are available to optimize the motor performance, set acceleration/deceler ation and forward/reverse speed limits, and add additional features and commands. The DCD can also be customized to simplify installation, and expand the voltage or current range. The main power DC bus can be operated from a 24 VDC to 48 VDC source. The Internal Switching Power Supply (IPS) used to bias the control circuits can be powered from the main power, or from a separate supply for an added level of safety. For applications involving dual drive axis, the amplifiers can be operated as a master and slave. In this mode, the master receives its command and sends a current command to the slave amplifier through an RS422 serial port to create a digital equivalent of a differential drive. In addition, the motor temperature, base plate temperature, fault information, limit switch data, and current feedback are also communicated via the serial bus. A unique "Get Me Home" mode is included in the DCD's extensive protection circuits to protect both the amplifier and motor, and is designed to gradually shut down the drive. Two LEDs provide visual indication of the drive's status for simple diagnosis. The DCD's NEMA 1 enclosure is designed to protect the internal electronics from contact and dust, and an aluminum base plate is used for mounting and heat sinking. Other NEMA enclosures are available upon request.
