What is CANopen DS402?
The DS402 (previously known as DSP402) is the reference profile for drives and motion controllers based on the standard CANopen protocol (introduced and managed since 1995 by the CiA group, CAN in Automation).
Originally used only on CANbus fieldbuses, the CANopen protocol, in recent years, has also been widely used in other much faster and high performance fieldbuses such as EtherCAT.
Today CANopen and DS402 are part of the IEC 61800-7 standard.
What are the advantages of CANopen DS402 (IEC 61800-7-201)?
A profile defines a device as 'standard' and, as such, it has to respect basic rules and functionality. Mandatory features are required to ensure that operation is possible.
The advantages of the approach to CANopen DS402 profile are:
- system integration
- standardization of the device
The profile obliges the device manufacturer to meet the required standard requirements and, consequently, it greatly reduces the effort required in integrating the system into an application.
Ever Elettronica Ethercat and Canopen DS402 drives
Ever Elettronica, as mentioned, has been one of the first Italian companies to implement and validate the CANopen protocol and the DS402 on its drives for stepper motors and brushless motors, starting from the early 90s.
In 2012, EtherCAT fieldbus was introduced, obtaining conformity certification through the 'Beckhoff ET9400 Conformance Test'.
Ever Elettronica EtherCAT drives implement the (CoE) CAN application protocol over EtharCAT.
ATo date, Ever Elettronica drives for stepper motors and brushless motors have been used and approved for many years on different types of applications with the main manufacturers of Ethercat and CANbus PLC masters on the market (Omron, Beckhoff, etc).
EtherCAT and DS402 are available on all types of Ever Elettronica drives for stepper motors and brushless motors (brushless DC and brushless AC). The potential of EtherCAT and DS402, associated with the vector control of the motor current and the management of the torque control of Ever Elettronica drives, guarantee an highly performing and reliable product.
Ever Elettronica drives for stepper motors and brushless motors (brushless DC and brushless AC) ensure accurate and precise tracking of the motion trajectories generated and required by the EtherCAT master with CSP, CSV, CST interpolated modes, even in the presence of high tracking dynamics.
Moreover, they ensure smooth movements, damping of vibrations and motors resonances and a drastic reduction in noise and motors overheating.
