🔧 Kaifull Unveils Upgraded EtherCAT Closed-loop Stepper Driver: Y2SS3H-EC
Kaifull Electronic Technology (Guangdong) has launched thenext-generation EtherCAT-based closed-loop Stepper Driver Y2SS3H-EC, delivering superior performance, greater compatibility, and a broader range of industrial applications.

🚀 Smarter Performance in a Smaller Package
The Y2SS3H-EC is a high-performance, EtherCAT-controlled stepper motor driver that integrates closed-loop technology to enhance control precision and reliability. As a standard EtherCAT slave, it supports CANopen over EtherCAT (CoE) and is compatible with a wide range of AC18~50V power inputs.
Despite its compact dimensions (118mm x 75.5mm), the Y2SS3H-EC offers powerful features usually found in larger and more complex drivers—making it ideal for smart factories and space-constrained automation environments.
🔍 Key Features of Y2SS3H-EC:
-
High Compatibility: Supports CiA402 standard protocol and integrates seamlessly with popular PLCs and motion controllers such as Beckhoff, Omron, Keyence, Advantech, Delta, and more.
-
Compact Design: 20% smaller footprint compared to similar EtherCAT stepper drivers in the market.
-
Easy Setup: Equipped with a new Type-C debugging interface, allowing configuration in just 3 steps.

🔌 Power & Motor Matching Advice
To achieve optimal high-speed performance, a higher input voltage is recommended within the specified range. Power supply current should be 1.1–1.3 times the driver’s output current. Motor selection should be based on actual load requirements—Kaifull provides free consultation for motor sizing and application support.
