Whether you need reliability, efficiency, or both, the Low Voltage L110I-C/L110I-E is your ideal solution for motion control needs.

Built-in Servo Drive Communication Protocols

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.

Friction Brake Inside

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.
