Kaifu Technology’s heavyweight product, Y2SS3-EC closed-loop bus stepper driver, perfectly integrates closed-loop control technology into stepper motors and greatly expands the functions of EtherCAT, with new excellent performance and a wide range of application fields. Y2SS3-EC is a high-performance bus controlled closed-loop stepper motor driver. The drive is equipped with the EtherCAT communication protocol, which can serve as a standard EtherCAT slave and support CANopen over EtherCAT (CoE); It can also be used with various closed-loop stepper motors of different sizes.
EtherCAT ® It is a registered trademark and patented technology authorized by Beifu Automation Co., Ltd. in Germany.
The Y2SS3-EC dual port RJ-45 connector is a 100BASE-TX (100Mbps) compliant interface that can be connected using standard Ethernet cables. Please use CAT5 or CAT5e (or higher level) Ethernet cables. The Ethernet input interface IN is connected to the Ethernet output interface OUT of the previous driver on the controller or bus. The Ethernet output interface OUT is connected to the Ethernet input interface IN of the next driver on the bus. If the driver is the last node on the bus, only the Ethernet input interface IN needs to be connected. No need to use terminal matching resistors.
Y2SS3-EC supports both synchronous and asynchronous EtherCAT control modes. In synchronous motion mode, the master station performs trajectory planning and outputs cycle instructions. The driver receives planning instructions from the master station according to the synchronization cycle, making it suitable for multi axis synchronous motion. Y2SS3-EC synchronous motion mode supports cyclic synchronous position mode (CSP). In the cyclic synchronous position mode (CSP), trajectory planning is completed at the master station. The position information sent by the master station is received based on the synchronization cycle, and the position information is immediately transmitted to the driver when the synchronization signal arrives. The synchronization cycle supported by Y2SS3-EC is; 1000 us, 2000 us, 4000 us.

2、 Power selection:
The power supply voltage of the driver can work normally within the specified range. If you need the motor to achieve better high-speed performance, you need to increase the power supply voltage of the driver.
The power supply current is generally determined based on the output phase current of the driver. Normally, the power supply current of the driver can be 1.1 to 1.3 times the output current of the driver.
At the same time, the magnitude of the input current of the power supply is also related to the speed and load of the motor during operation. Therefore, for specific application scenarios, users need to conduct specific analysis and estimation.
3、 Motor selection:
Y2SS3-EC can output a maximum current of 7A and is suitable for two-phase DC stepper motors with flange sizes of 86 and below.
Y2SS3-EC has the characteristic of integrating open and closed loops, and both open-loop and closed-loop stepper motors are compatible.
The selection of stepper motors must be calculated and confirmed based on the load of relevant institutions. You can contact the hotline of Kaifu Technology Company (400-960-1069) to inquire about the specific method of motor selection!

5、 Mechanical dimensions:
*It is recommended to install vertically on the side to create strong air convection through the heat dissipation teeth. If necessary, install a fan near the driver to force heat dissipation and ensure that the driver operates within a reliable temperature range.
6、 Drive connection instructions:
In order to better meet market demand, Kaifu Technology has launched a new bus driver Y2SS3-EC. Compared to the old EEDC and EEDO series as well as bus drivers on the market, the new Y2SS3-EC has the following characteristics. Welcome new and old customers to inquire, obtain samples, and call for consultation!
1、 Superior performance:
① Due to the use of advanced high-end servo synchronization technology, it is easy to achieve synchronization control of over 100 axes within a 2ms loop cycle;
② Reducing motor heating Y2SS3-EC closed-loop adopts modeling equivalent technology to achieve automatic adjustment of current amplitude in step mode, reduce heating, and achieve high-speed and fast response of position loop, maintaining the rigidity of the original open-loop stepper driver.
③ When the motor torque and control response time Y2SS3-EC are increased by the same current, the motor torque is generally increased by 5% -10%, and the control response time is increased by 30%. Within the rated load range, almost one code disk pulse control accuracy can be achieved.
2、 Strong adaptability:
① Built in virtual buttons to select motor parameters, after selection, it can run almost without adjusting parameters, and parameter adjustment is simple.
② Y2SS3-EC has developed a high-end servo control loop and ECAT high-precision clock real-time synchronization adjustment technology, which can almost adapt to all controllers on the market. It has built-in interpolation time automatic detection and adjustment, and can operate parallel without the need for manual adjustment.
3、 High cost-effectiveness:
① Material reduction: Y2SS3-EC is open loop compatible and can be paired with a 20mm-86mm series stepper motor, achieving the desire of customers to use a bus type stepper motor with only one driver.
