According to a report from Electronic Enthusiasts (by Li Ningyuan), in the current motion control field, bus technology and drive technology complement each other. In traditional motion control systems, the control methods are relatively singular. Generally, pulse or analog signals are used as control signals, which are sent to the motor driver, and then the … Read more

CANopen is a high-level protocol based on the CAN (Controller Area Network) serial bus system and CAL (CAN Application Layer). CANopen assumes that connected devices have hardware with a CAN transceiver and a CAN controller that comply with the ISO 11898 standard. The CANopen communication protocol CiA DS-301 includes periodic and event-driven communication, which not … Read more
1.Device Control This section mainly describes how the master controls the driver through the CANopen bus, such as turning the servo ON or clearing alarms. (1)Control State Machine The master controls the driver through the control word, and by reading the driver’s status word, it can know the current state of the driver. This section … Read more

From the OSI network model perspective, fieldbus networks generally implement only the 1 layer (Physical Layer), the 2 layer (Data Link Layer), and the 7 layer (Application Layer). Because fieldbus typically includes only one network segment, it does not require the 3 layer (Transport Layer) and the 4 layer (Network Layer), nor does it need … Read more
1ãCANopenPredefined Connection Set To reduce the configuration workload of simple networks, CANopen defines a mandatory default identifier (CAN-ID) allocation table. These identifiers are available in the pre-operational state and can be modified through dynamic allocation. CANopen devices must provide the corresponding identifiers for the communication objects they support. The defaultID allocation table is based on … Read more
In the development process of CAN/CANopen products, configuring the object dictionary is a crucial step. Users need to have a sufficient understanding of the CANopen protocol, knowing the potential variables and transmission types in the device. It is also necessary to ensure that the design process does not violate the relevant definitions of the CANopen … Read more
