9 P art 2: DSP-402 Implementation Section 2 Accessing The MDrivePlus CANopen Introduction The access from the CAN network to the drive is done through data objects. Process Data Object (PDO) PDOs are messages in an unconfirmed service. They are used for the transfer of r eal-time data to and from the drive.
10 MDrivePlus CAN open R020507 PDO Mapping The MDrivePlus CAN open allows you to map objects to PDOs to reduce the transfer application data more efficiently . By using the PDO the user can map a PDO to multiple objects (8 Data Bytes max.) The example will show RPDO 1400 h mapped to Control W ord (6040 h ) and T arget P osition (607A h ).
