Kaifu Technology’s blockbuster product Y2SS3-EC closed-loop bus stepper driver perfectly integrates closed-loop control technology into 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. EtherCAT communication protocol is built into the drive. It can be used as a standard EtherCAT slave, supporting CANopen over EtherCAT(CoE). 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 Befo Automation GMBH in Germany.

The Y2SS3-EC two-port RJ-45 connector is a 100BASE-TX(100Mbps) port and can be connected using standard network cables. Use CAT5 or CAT5e(or higher level) 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 connects to the Ethernet input interface IN of the next drive on the bus. If the drive is the last node on the bus, you only need to connect the Ethernet input interface IN. There is no need to use a terminal matching resistor.

Y2SS3-EC supports synchronous mode and non-synchronous mode EtherCAT control mode. In synchronous motion mode, the master station carries out trajectory planning and outputs periodic instructions, and the driver receives planning instructions from the master station according to synchronous cycle, which is suitable for multi-axis synchronous motion. Y2SS3-EC Synchronous motion mode Supports cyclic synchronous position mode (CSP). In cyclic synchronous position mode (CSP), trajectory planning is completed at the master station. The position information sent by the master station is received according to the synchronization period, and the position information is immediately transmitted to the driver when the synchronization signal arrives. The synchronization period supported by Y2SS3-EC is: 1000 us, 2000 us, 4000 us.
