CANopen Solutions
 
 
The CAN (Controller Area Network) bus is one of the safest industrial network systems, and CANopen is the standard industrial communication protocol on the CAN bus. CANopen technology has been used in a wide range of application fields, including medical equipment, vehicles, railway applications or building automation. ICP DAS provides a motion control library (CiA 402) for CANopen Master products meaning that users can now integrate motion control systems into a CANopen network, providing the ability to control CANopen based motors and remote I/O devices within the same network, making wire connections and control easier and more efficient.

The CANopen Motion Library is compliant with the CANopen standard CiA 402, and provides a variety of motion control functions, such as position control, velocity control, torque control, synchronous action etc. The CiA 402 is one of the standard CANopen application profiles, and is specially designed for motion control systems. In addition to making the management of the CANopen-based motors easy, the CANopen protocol, which is based on the CAN bus, can help to reduce the need for wire connections between the controller and the motors, and provides rapid troubleshooting functions. A large number of CANopen-based motors can be linked together so that multi-axis motion control via a single host becomes achievable. While controlling the motors, CANopen-based remote I/O modules that comply with the CiA 402 standard can also be accessed at the same time. Therefore, developing a motion control application becomes easier and more convenient.

Benefits:
  • Suitable for distributed multi-axis motion control systems.
    E.g., distributed sun tracker systems, conveyer transmission control systems, and so on.
  • Reduces the cost of wiring, especially time requirements.
  • Choose from a range of motors with no limit on certain types.
  • The CAN hardware has a range of error detection and error correction mechanisms, which provides the safest communication bus.
  • Able to use different CANopen I/O modules and motors in the same CANopen network.
  • The range of the CANopen bus can be extended for long distance applications.
    For example, for solar or wind farm application systems.
  • The CANopen bus can be converted to fiber to protect against high noise interference.

CANopen Motion Applications:
1. Corrugated Carton Cutting Machine
A creasing and cutting machine is one kind of equipment for creasing and cutting ordinary cardboard corrugated board plastic and leather in general, applicable to printing packaging decoration and plastic industries. Machine is characterized by compact structure, fine workman ship, big pressure, and high precision and easy and reliable operation. With high degree of automation, this model can do integrative process of auto-feeding, cutting and autounloading. All the cutting knives and rollers are controlled by 31 CANopen motors. The WP-8441 and I-8123W play the role of the CANopen master to control all the motors simultaneously.
 
2. Solar Tracking System
Solar Tracking System is a distribute device for orienting a solar panel or concentrating a solar reflector or lens towards the sun. The sun's position in the sky varies both with the seasons and time of day as the sun moves across the sky. The solar energy intercepted by the solar panels during the course of the day is not maximized if the position of the panel is always static. Dynamically oriented solar panels can track the sun throughout each day to greatly enhance energy collection. There are more than 100 motors in that system. The tracker built-in one or two axis motors. The PC and PISO-CPM100 control parts of the solar panels.
