Today I will introduce a cutting-edge motion control technology – EtherCAT bus control. As a popular motion control method in recent years, EtherCAT bus control has the following three advantages:
1. Ultra-fast transmission: Among Ethernet control protocols, EtherCAT bus control protocol stands out for its excellent transmission speed and is one of the fastest protocols.
2. Flexible device integration and expansion: All devices that support EtherCAT bus control, such as drivers and IO modules, can be easily incorporated into the EtherCAT bus control system to achieve convenient device integration and expansion.
3. Simplify wiring and reduce costs: EtherCAT bus control greatly simplifies wiring work, only one network cable is needed to connect the EtherCAT bus control card to the driver and IO module and other devices, and the peripheral IO input and output wiring can be directly connected to the driver or bus module IO port, thus significantly reducing the wiring cost.
Next, I’ll cover the configuration, wiring, and programming of the EtherCAT bus control system. First, EtherCAT’s system configuration, taking Googo’s EtherCAT bus control card as an example, can connect to servo drives, stepper drives, and other devices that support EtherCAT bus control. This extension is very convenient and requires only a network cable connected to the EtherCAT bus control card. At the same time, the Glink bus can be used to control the input and output of digital and analog quantities, such as solenoid valves, indicators, etc.
EtherCAT control system, simply connect the network cable from the interface of the EtherCAT control card to the EtherCAT drive. The drive can be connected to the next drive while the drive is connected to our servo motor and encoder. Dedicated IO signals can be connected to the bus driver’s IO port, including origin signals, limit signals, etc. The bus driver can be connected to our motor platform locally, and the bus IO module can also be connected to the solenoid valve, sensor, etc., which greatly simplifies the wiring and is conducive to the continuous expansion of the equipment.
EtherCAT control card programming and general control card similar, just a little understanding of the initialization control business card printing, origin acquisition and dedicated IO signal reading and other differences, if you are familiar with general control card programming, then palm
Programming with the bus control card is not difficult.
As a high performance and high reliability motion control mode, EtherCAT bus control has been paid more and more attention in the field of industrial automation. For engineers who want to learn more about control system technology, mastering EtherCAT bus control technology is very necessary.
