SV33xx | Pulse-Type Servo Driver

The SV3 series of servo products were launched in 2023 and are divided into the SV33 general-purpose servo and the SV35 high-performance servo. Both the SV33 and SV35 series support dynamic braking and weak magnetic functions and feature advanced capabilities such as one-touch auto-tuning, notch filters, and vibration suppression. These features greatly reduce setup time and enhance vibration suppression, improving following performance and shortening tuning time through the addition and improvement of vibration suppression functions.

The SV33 series servos are general AC servo products independently developed by Sinsegye, offering features such as inertia identification and automatic gain adjustment, making the drivers easy to use. The power range of this series is 0.05kW to 2kW, and it supports communication protocols such as pulse and EtherCAT. The SV33 series boasts extreme power density, more than three times overload capacity, a 3kHz speed loop bandwidth, and performance that is at the industry-leading level.
