Integrated Servo Drive Communication Protocols for Enhanced Control

The integrated servo drive of our actuators supports multiple advanced communication protocols, including EtherCAT, CANopen, and Modbus, ensuring seamless integration into a variety of industrial systems. The drive offers real-time adjustability for position, speed, and current loop PID settings, providing precise control and flexibility.

Integrated Dual Absolute Encoder with Dual-Loop Position Control

The actuator features a built-in dual absolute encoder system, offering exceptional precision and reliability. The 16-bit absolute multiturn encoder on the output shaft provides outstanding repeatability of up to ±7 arc seconds, ensuring highly accurate positioning.

Key Features:

• Absolute Position Accuracy: Achieves accuracy of up to ±15 arc seconds, ensuring precise control at all times.
• Power-Off Reliability: The encoder retains absolute position and multi-turn counter even during power-off, ensuring consistent performance and eliminating the need for recalibration upon restart.
• Dual-Loop Position Control: Enhances position control accuracy, providing better response and stability in demanding applications.

Internal Friction Brake for Smooth, Stable Operation

The actuator is equipped with a friction brake that ensures smooth and stable braking
performance. It operates with no gaps and no backlash, providing precise control without any loss of motion.

Key Features:

• No Movement Upon Power-On: The brake remains engaged at power-up, preventing
  unwanted motion without wear and tear.
• Durable and Maintenance-Free: Designed for long-term use, the friction brake ensures reliable performance without the need for regular maintenance.
• Emergency Stop Capability: The brake can also function as an emergency stop, offering additional safety in critical situations.
