Pwodwi Entwodiksyon

The S3A is a digital AC servo spindle driver that adopts full-digital and vector control technologies. It is compatible with motors ranging from 3.7kW to 37kW, operates on three-phase AC 380V input, and offers a speed regulation range of 1-30000 r/min.

Integrating speed, position, and torque control in one, it supports multiple encoders as well as functions like rigid tapping and spindle orientation. Featuring full-closed-loop high-precision control, it ensures high reliability and excellent speed stability.

The driver is compatible with various position feedback components, built-in motorized spindles, 3.7-37kW motors, and three-phase AC 380V power supply, capable of driving both spindle motors and built-in motorized spindles.

: Adopts full-digital control and vector control technologies for precise and responsive operation.

: Equipped with industrial-grade IPM modules to handle sudden load surges effectively.

: Boasts excellent dynamic acceleration/deceleration performance and low-speed characteristics for smooth spindle rotation.

: Incorporates multiple protection mechanisms against overvoltage, overcurrent, overload, and other faults.

: Supports dual encoders and multiple communication types, adapting to diverse industrial setups.
