What is EthercatCAT? What are the benefits of choosing a spring machine equipped with EthercatCAT?
Simply put, EthercatCAT is an Ethernet-based command communication protocol. This communication protocol is mainly used to standardize motor manufacturers to manufacture products that can accept the same operating commands. The CAT of its name is an acronym for Control Automation Technology. This directive standard was first proposed by BECKHOFF in Germany, and now more than 5,000 members around the world have joined the association.
The benefits of choosing an EthercatCAT spring machine are as follows:
Although the commonly used pulse-wave type servomotor claims to be able to reach a speed of 4Mbps, the pulse-wave output of the traditional controller will cause the problem that the driver needs to calculate while it is running, which indirectly causes the tuning and positioning effect of the motor to be poor. EthercatCAT's approach is to directly execute the stroke command required for work piece manufacturing. Because the command format is directly input into the driver, the driver does not need to calculate while running, so the positioning can be more accurate, resulting in faster motor performance speed.
Larger Production Capacity
As mentioned above, having a faster speed and a faster tuning system means that the productivity of the machine and the accuracy of the product will increase.
Traditional controllers are driven by output pulses, and most industrial computer motherboards on the market are single-core drivers. Theoretically, the limit of synchronous coaxial is about 10 axes, and the limit of different axes is about 20 axes.
EthercatCAT executes synchronous operation commands over network cables. The network can currently be upgraded to bandwidth of 1Gbps and the drives operate at 4Mbps. In this architecture, a theoretical number of axes are 250 synchronized axes.
The EtherCAT Technology Group is now the largest fieldbus organization in the world, with more than 100,000 accessory and servomotor manufacturers worldwide following this specification. Users thus can benefit from the advantages of each manufacturer. For example, if a certain axis of your equipment needs to be waterproof, you can adopt a certain brand of waterproof motor, and motors without waterproof requirements can use other non-waterproof brands, or choose high-speed or economical models to increase machine efficiency or save costs. It is even possible to use motors produced in Germany, Japan, and the United States with each other in the same machine. And as long as the network cables are used to connect each other in series, the huge and complicated wiring work can be saved.
Towards Industry 4.0
Because EthercatCAT integrates most of the signal output formats of motor manufacturers, when there is a problem with the equipment's servomotor or module, it can send a message to the host through EthercatCAT. For example, a certain axis motor failure, insufficient oil supply to the equipment, abnormal air pressure, opening of the safety door, or even pressing the emergency stop. These messages can be displayed on the user interface through the BECKHOFF host, and can also inform the equipment manufacturer's engineers, even on the other side of the earth, about the equipment abnormality. When new features are released, the software can also be updated through the Internet.
Xinda Machinery is one of the few spring machine manufacturers to join the EtherCAT Technology Group in 2019. Its camless spring machine and skateboard spring machine are equipped with EtherCAT master protocol chip.
