CANOPEN-VACON NX INTERFACE

CanOpen communication objects transmitted via the CAN network are described by services and

protocols. They are classified as follows:

The real-time data transfer is performed by the Process Data Objects (PDOs) protocol



REAL-TIME CONTROL OF THE DRIVE

Service Data Objects (SDO) protocols provide the read and write access to entries of a device

object dictionary



CONFIGURATION OF THE DRIVE, READ/WRITE DRIVE PARAMETERS

The Network Management (NMT) protocols provide services for network initialization, error

control and device status control



START/STOP CANOPEN COMMUNICATION

COB-ID

The identification field of the CANopen-message is 11 bits.

ID-Bit

COB-ID

Function Code

Module-ID

The default identification field consists of a functional part and a module-ID part. The functional part

determines the object priority. This kind of identification field allows communication between a

master and 127 slaves. Broadcasting is indicated by a module-id of zero. Function codes are

determined with object dictionaries in device profiles.
