HSD7 series high-end synchronous servo drive
HSD7 series synchronous AC servo driver adopt advanced control algorithm, support mainstream protocol such as MODBUS, CANOPEN, EtherCAT, MECHATROLINK. Encoder resolution up to 24bits. STO and Full colse loop function is optional, response up to 3.1KH.

HSD7 new series high-end synchronous AC servo driver adopt the advanced control algorithm, support mainstream protocol such as MODBUS, CANOPEN, EtherCAT, MECHATROLINK which can realize speed and accurate position control. With intelligent power module (IPM) and other latest technology design, simple operation, high reliability, small size, easy to install.

Encoder resolution can up to 24bits, support 17bit increamental and 17bit/23bit/24bt absolute type encoder. 

STO &Full colse loop function is optional.

Speed loop response frequency up to 3.1KHz.

Adjustment-free function,  Self-tuning function.

Friction&backlash compensation function.

This servo driver has mature servo technology and the highest cost performance.


1. Main circuit power supply:  Three-phase AC220V, 50/60Hz;  Three-phase AC380V, 50/60Hz;

2. Speed loop response frequency up to 3.1KHz.

3. Adjustment-free function,  Self-tuning function.

4. Debugging software with powerful function, friendly interface and easy-to-use.

5. Friction&backlash compensation function.

6. STO &Full colse loop function is optional.

7. Control mode: Position control, Speed control, Torque control, JOG operation, speed contact, etc.

8. Encoder feedback:

    Ordinary incremental encoder: 2500 lines incremental standard type, 2500 lines incremental saving line type.

    Serial encoder:17bits/ 23bits/24bits absolute value encoder.

9. Communication: Standard MODBUS, CANOPEN, EtherCAT, MECHATROLINK.

10. Speed control range: 1:5000( in the stable running without crawling at the rated load);

11. Digital Input terminal: photoelectric coupling  isolation, functional programmable, can realize servo ON (/ S - ON),       P action (/P - CON), not forward the side drive (P-OT), not reverse side drive (N-OT), alarm reset (/ALM-RST),          forward side torque limit (/P-CL), internal set speed switch and so on

12. Digital output terminal: functional programmable, can realize servo alarm (ALM), position completion            (/COIN), speed consistency inspection (/V-CMP), servo motor rotation detection (/TGON), servo ready 

      (/S-RDY),  torque limit detection (/CLT), brake (/BK), encoder zero output (PGC).

13. Over travel (OT) prevention function: Dynamic brake (DB) stopping, decelerate stopping, or free running stop             when it is at P-OT, N-OT input action

14. Protection function: Over current, overvoltage, under voltage, overload, over speed, regeneration fault, encoder          feedback error, etc
