Description

The Danfoss MC400 microcontroller is a multi-loop controller that is environmentally hardened for mobile off-highway open and closed loop control system applications. A powerful 16-bit embedded microprocessor allows the MC400 to control complex systems as either a stand alone controller or as a member of a Controller Area Network (CAN) system With 6-axis output capability, the MC400 has enough power and flexibility to handle many machine control applications. These could include hydrostatic propel circuits, open and closed loop work functions and operator interface control. Controlled devices may include electrical displacement controllers, proportional solenoid valves and Danfoss PVG series control valves.
The controller can interface with a wide variety of analog and digital sensors such as potentiometers, Hall-effect sensors, pressure transducers and pulse pickups. Other control information can also be attained via CAN communications.
Actual I/O functionality of the MC400 is defined by application software that is loaded into the controller’s flash memory. This programming process can occur at the factory or in the field via a laptop computer’s RS232 port. WebGPI ™ is the Danfoss communication software that facilitates this process, and allows for various other user interface features.
The MC400 controller consists of a state-of-the-art circuit board assembly inside an aluminum die-cast housing. Two connectors designated P1 and P2 provide for electrical connections. These individually keyed, 24-pin connectors provide access to the controller’s input and output functions as well as power supply and communication connections. An optional, on board 4-character LED display and four membrane switches can provide additional functionality.

Features

• Robust electronics operates over a range of 9 to 32 Vdc with reverse battery, negative transient and load dump protection.
• Environmentally hardened design includes coated die-cast aluminum housing that withstands harsh mobile machine operating conditions including shock, vibration, EMI/RFI, high pressure wash down and temperature and humidity extremes.
• High performance 16-bit Infineon C167CR microprocessor includes on board CAN 2.0b interface and 2Kb of internal RAM.
• 1 MB of controller memory allows for even the most complex software control applications. Software is downloaded to the controller, eliminating the need to change EPROM components to change software.
• Controller Area Network (CAN) communication port meets the 2.0b standard. This high speed serial asynchronous communication allows for information exchange with other devices equipped with CAN communications. The baud rate and data structure are determined by the controller software allowing support for protocols such as J-1939, CAN Open and the Danfoss S-net.
• The Danfoss standard four LED configuration provides system and application information.
• An optional 4-character LED display and four membrane switches provide for easy setup, calibration and troubleshooting information.
• The six PWM valve driver pairs offer up to 3 amps of closed loop controlled current.
• Optional valve driver configuration for up to 12 Danfoss PVG valve drivers.
• WebGPI™ user interface.
• Robust electronics operates over a range of 9 to 32 Vdc with reverse battery, negative transient and load dump protection.

Application Software

The MC400 is designed to run control solution software engineered for a specific machine. There are no standard software programs available. Danfoss has an extensive library of software objects to help facilitate the software development process. These include control objects for functions such as anti- stall, dual-path control, ramp functions and PID controls. Contact Danfoss for additional information or to discuss your specific application.

Ordering Information

• For complete hardware and software ordering information, consult the factory. The MC400 ordering number designates both hardware configuration and application software.
• Mating I/O connectors: Part number K30439 (bag assembly contains two 24-pin Deutsch DRC23 series connectors with pins), Deutsch crimp tool: model number DTT-20-00
• WebGPI™ communication software: Part number 1090381.
