Brushless DC Servo Motor With integrated CANopen Controller Supporting CiA 402 Device Profile

Nanotec PD2-C-IP — BRUSHLESS DC SERVO MOTOR WITH INTEGRATED CONTROLLER (STEPPER MOTOR) AND PROTECTION CLASS IP65 – NEMA 17For use in harsh environmental conditions, Nanotec (Germany) developed the PD2-C-IP, a brushless DC servo motor with integrated controller and 42 mm flange size in protection class IP65.v.

The PD2-C-IP is available as a brushless DC motor, with an operating voltage of 12 V to 48 V and a rated power of 105 W, and as a stepper motor with a nominal torque of up to 0,5 Nm. Due to the field-oriented control based on an integrated encoder, both motors are controlled in the same way and differ only in their working point. Each motor is available in a CANopen and in a USB version.

In the CANopen version, the motor can be controlled via the CiA 402 device profile. In the USB version, the motor can be parameterized and programmed for standalone operation. The USB port is covered by a waterproof cap, and the motor operates on the basis of the digital and analog input signals in combination with the stored program. For pin-out the motor is equipped with M8 connectors (except USB).

Embedded Networking with CAN and CANopenCAN (Controller Area Network) is a serial communication protocol that was originally developed for the automobile industry. CAN is far superior to conventional serial technologies such as RS232 in regards to functionality and reliability and yet CAN implementations are more cost effective. CANopen, a higher layer protocol based on CAN, provides the means to apply the ingenious CAN features to a variety of industrial-strength applications.

Many users, for example in the field of medical engineering, opted for CANopen because they have to meet particularly stringent safety requirements. Similar requirements had to be considered by manufacturers of other equipment with very high safety or reliability requirements (e.g. robots, lifts and transportation systems). Providing a detailed look at both CAN and CANopen, this book examines those technologies in the context of embedded networks.

There is an overview of general embedded networking and an introduction to the primary functionality provided by CANopen. Everything one needs to know to configure and operate a CANopen network using off-the-shelf components is described, along with details for those designers who want to build their own CANopen nodes. The wide variety of applications for CAN and CANopen is discussed, and instructions in developing embedded networks based on the protocol are included. In addition, references and examples using MicroCANopen, PCANopen Magic, and Vector’s high-end development tools are provided.
