CAN in Automation (CiA), the international CAN users’ and manufacturers’ group, has released a version of the CiA 402-2 CANopen profile for drives and motion controllers. Version 4.1 specifies the operation modes and the parameters in detail and is based on the IEC 61800-7-201 standard. The improvements include some editorial improvements and mainly error corrections. It is intended to introduce the changes into the IEC standard as early as possible.

In addition, the association has released CiA 402-6. This part describes the process data object (PDO) mapping for CANopen FD. It comprises several sets of pre-defined PDOs. One is for single servo drives and stepper motors, another for single-axis frequency inverters, and a third one for multi-axes devices. In particular, PDO set for multiple-axes allows controlling simultaneously up to motors with one message. The specification also introduces the valid PDO mapping entries parameters for TPDOs and RPDOs.

"The CiA 402 series is the most implemented drive profile," said Holger Zelwanger, CiA managing director. "Part 6 is the first CANopen profile making use of the longer payload in CAN FD messages. This improves the system design and allows to use CAN also in challenging motion control applications."
