Kaifu Technology's blockbuster product Y2SS3-EC closed-loop bus stepper driver, the product perfectly integrates closed-loop control technology in the stepper motor, and greatly expands the function of EtherCAT, with a new excellent performance and a wide range of applications. Y2SS3-EC is a high-performance bus-controlled closed-loop stepper motor driver. The driver has built-in EtherCAT communication protocol, which can be used as a standard EtherCAT slave station, supported by CANopen over EtherCAT(CoE). At the same time, it can also be used with a variety of closed-loop stepper motors of different sizes.

EtherCAT® is a registered trademark and patented technology licensed by Beckhoff Automation GMBH.

The Y2SS3-EC two-port RJ-45 connector is a 100BASE-TX(100Mbps) compliant interface that can be connected using standard network cables. Use CAT5 or CAT5e(or higher) network cables. The Ethernet input interface IN is connected to the Ethernet output interface OUT of the previous drive on the controller or bus. The Ethernet output interface OUT is connected to the Ethernet input interface IN of the next drive on the bus. If the drive is the last node on the bus, just connect the Ethernet input interface IN. No need to use a terminal matching resistor.


Second, the choice of power supply:

The driver supply voltage can work normally between the specified range, if you want the motor to get better high-speed performance, you need to increase the driver supply voltage.

The power supply current is generally determined by the output phase current of the driver. Under normal circumstances, the driver power supply current can be 1.1 to 1.3 times the driver output current.
At the same time, the size of the power input current is also related to the speed and load of the motor during operation, so for specific applications, users need to carry out specific analysis and estimation.

Third, the selection of motor:

Y2SS3-EC can output up to 7A current and can be adapted to two-phase DC stepper motors with flange sizes of 86 and below.

Y2SS3-EC has an open-loop integrated feature, and can be compatible with open-loop or closed-loop stepper motors.

Stepper motor selection must be calculated according to the load of the relevant institutions to confirm, can contact Kaifu technology company hotline (400-960-1069) to consult the specific method of motor selection!
