High-Performance Spindle Motor Drive for CNC Grinders and Machining Centers

Product Overview

The S6 series is a specialized servo drive engineered specifically for spindle applications in CNC machining equipment. It is built with a brand new design framework that delivers enhanced functionality and flexible configuration options. The drive is ideal for controlling spindle motors in CNC lathes, CNC milling machines, machining centers, grinders, and other precision CNC equipment.

Product Features

Wide Power Coverage
The S6 series is available in 220V models ranging from 2.2kW to 5.5kW and 380V models ranging from 4.0kW to 11kW, making it suitable for a broad spectrum of machine tool applications.

Exceptional Overload Capability
The drive provides 150% rated output current for 60 seconds and 200% rated output current for 8 seconds, ensuring reliable performance during heavy cutting and sudden load changes.

Intelligent Motor Self-Tuning
The built-in self-learning function automatically identifies motor parameters and mechanical characteristics, significantly reducing commissioning time and ensuring optimal performance even with third-party motors.

Precision Position Control
The drive supports both semi-closed loop and full closed loop position control modes, achieving positioning accuracy of ±1 pulse for high-precision machining operations.

Multi-Interface Compatibility
The S6 series supports multiple CNC interface options including analog pulse, EtherCAT bus, and M3 bus, allowing seamless integration with various CNC systems.

Comprehensive Encoder Support
It is compatible with TTL differential output, Tamagawa absolute value, SinCos, and SSI/BISS protocol encoders. The drive also supports arbitrary frequency division output for flexible system design.

High-Speed Field Weakening Performance
The drive maintains strong torque output even in the field weakening region, enabling high-speed spindle operation without sacrificing performance.

Compact Structural Design
The S6 series features a revolutionary compact design, occupying 46% to 55% less space than the previous S5 series, which helps reduce cabinet size and installation costs.

Dust-Proof Air Duct Design
The independent air duct design effectively prevents dust and contaminants from entering the drive, reducing the risk of short circuits and improving long-term reliability.

Efficient Thermal Management
Equipped with large air volume, long-life cooling fans, the drive maintains low internal temperatures even under continuous heavy-duty operation, ensuring stable and reliable performance.

Robust Hardware Architecture
The integrated IGBT module with generous design margin delivers superior stability compared to discrete IGBT solutions. The drive also features reliable overcurrent protection, short circuit protection, and excellent anti-electromagnetic interference capability.

User-Friendly Maintenance Design
The motor encoder and spindle encoder interfaces are separated for simplified wiring and easier maintenance. The newly upgraded silicone keypad provides a more comfortable and responsive user experience.
