Positioning Controller With CANopen - CiA-402 Capabilities
maxon has launched a miniaturized controller that comes in a size of 32 mm x 22 mm as part of its product line of positioning controllers.
The controller's functionality, operation, software, and accessories are derived primarily from existing products in the EPOS4 range. The device is fitting for applications utilizing both brushed DC and brushless EC motors (BLDC) of up to 120 W.
It has extensive feedback options such as Hall sensors, as well as digital incremental and SSI absolute encoders. Concepts such as Dual Loop, Field Oriented Control (FOC), feedforward, and observer control provide optimal control for a variety of applications.
The current digital and analog inputs and outputs are easily configurable and matched to the many functions and operating modes of the CiA-402-compliant positioning controller.
The EPOS Studio start-up software, as well as libraries and programming samples for integration in a variety of master systems, are available free of charge. A plug-and-play EvaluationBoard (EB) is provided for initial commissioning.
The first derivative of this new micro design is the CANopen version, which can also be accessed via RS232 or USB connection. In the spring of 2020, the EPOS4 Micro 24/5 EtherCAT will follow as the second product of similarly small size.
CANgineBerry - CANopen Module for Raspberry Pi
The CANgineBerry for CANopen is an active CAN Bus co-processor module that uses a regular UART communication channel towards the host system. With its independent 32-bit microcontroller, the CANgineBerry can easily execute CAN Bus protocols with tough timing demands such as CANcrypt or CANopen with response times of under 10 ms.
Depending on the configuration, the CAN Bus communication can be up and running within 50 ms after power-on, even if the host system takes significantly longer to boot.
