CiA® 402 series: CANopen device profile for drives and motion control
![](/fileadmin/resources/images/knowledge/cia402.png)
This set of profile specifications standardizes the functional behavior of controllers for servo drives, frequency inverters, and stepper motors. It also introduces several operation modes and corresponding configuration parameters. The profile description includes a finite state automaton (FSA) that defines internal and external device behavior for each state. The state of the drive determines which commands are accepted and whether high power is applied. States are changed when a control-word from the host-controller is received. They can also be changed due to internal events. The current state is indicated by the status-word. The control-word and different command values (e.g. velocity) are mapped into default RPDOs (receive process data objects). The status-word and different actual values (e.g. position) are mapped into TPDOs (transmit process data objects).
This profile has been partly internationally standardized in the IEC 61800-7 series. The original CiA 402 part 2 is now IEC 61800-7-201. It describes all functional behavior including the FSA and all process data and configuration parameters. CiA 402 part 3 contains mainly the PDO definitions, nowadays published in IEC 61800-7-301. In February 2024, CiA has released the revised versions of CiA 402 part 2 and CiA 402 part 3. The updated parts introduce 64-bit position values and some additional operation modes. It is intended to update the IEC standards according to the recent CiA 402 parts as soon as it is possible.
The CiA 402 part 3 (included in the IEC standard) specifies a set of generic default PDOs available to all drives as well as a set of specific default PDOs applicable only to a specific class of drives such as servo drives, frequency inverters or stepper motors. CiA has developed a third set of standardized PDOs optimized for easy system integration (CiA 402 part 5). CiA 402 part 4 specifies the safety parameters and dedicated SRDO (safety-related data objects) parameters as defined in EN 50325-5 (CANopen Safety). This approach is based on the Generic Safety Drive Profile from Ethercat Technology Group (ETG). The CiA 319 framework provides guidelines to simplify the implementation and configuration of devices using CANopen Safety communication services.
In October 2016, CiA has released the CiA 402-6 specifying the default 64-byte PDO usage for CANopen FD networks. The PDO sets are defined for servo drives and stepper motors (use the same set), for frequency converters as well as for multiple-axes systems.
On the one hand, CiA 402 is one of the best-specified motion control profiles. On the other hand, the multitude of optional functions and parameters limits the exchangeability of devices compliant to CiA 402. Some vendors implement only a subset of the mandatory functions and parameters, but still claim CiA 402 conformity.

CiA 402-4 version 1.0.0CANopen device profile for drives and motion control - Part 4: Safety functionality | DescriptionThis series of profile specifies the CANopen interface of power drive systems. It is suitable for drive and motion controllers. It specifies several operating modes for frequency inverters, servocontrollers, and stepper motors. The series of profile is split in several parts: Part 1: General definitions, Part 2: Operation modes and application data, Part 3: PDO mapping, Part 4: Safety functionality, Part 5: PDO mapping superset. Part 2 and part 3 are substituted by the international standards IEC 61800-7-201 respectively IEC 61800-7-301. This part specifies the safety functionality for electrical drives and motion controllers compliant with the CiA 402 profile. It specifies the safety-related process data, the safety-related configuration parameters, and the safety-related diagnostic information as well as the SRDO communication and mapping parameters. Safety devices compliant with this part consume SRDOs containing commands from a control device and produce SRDOs containing status information to be received by the control device. Safety devices compliant with this document provide typically local safety functions as well as safety inputs and outputs. The safety outputs can be used to assign safety status information or can be set by the command information of the safety logic. The document is based on the ETG.6100.2 Generic Safety Drive Profile by the Ethercat Technology Group (ETG), and it specifies the mapping to CANopen. NOTE: The naming and the assigned indices and sub-indices of the parameters are far as possible the same as in the ETG documents. But some ETG parameters are represented in CANopen by two parameters, consequently two names are used. Keywordsn/a | DSP3.2 MiB | 2015-12-02Login |
