♦Dual-core processing efficiency is higher, the high motor runs smoothly, the vibration when stopping is lower, and the response is faster

♦ Simple and easy-to-understand menu display

♦ The DB series plug for convenient wiring, simple operation and easy welding

♦Supports CANopen/EtherCAT bus control, Meet the needs of high-end equipment.

♦SD20 supports fully closed-loop control and gantry synchronization, and the driver can adapt to a wider range of places.

Product Detail

SCH-SD20-G Universal servo

SD20-G Series Servo Drives is a high performance drive particularly suitable for general use. It has a 3.0kHz frequency response, which could meet the wide range of customer's requirement. The feedback options are incremental encoder, absolute encoder and resolver.

The rich functionality includes full close loop, multi-position control, gain switchover, moving fixed-length cutting, etc.

Built-in PLC is open for customer to make simple programming.

Widely used in robots, CNC machine tools, textiles, packaging and other industries.
