Servo Drive

Festo Servo Drive

The Festo servo drive delivers dynamic, accurate and energy-efficient motion control in modern automation systems. Built to integrate with Festo’s servo motors as well as third-party motors, it enables precise control of torque, speed and position — from point-to-point movements to interpolating multi-axis sequences.

These drives support a wide range of fieldbus and Ethernet protocols, including EtherCAT®, Ethernet/IP, PROFINET, Modbus and CANopen, making them suitable for complex, networked control systems. 

⭐ Important: This servo drive provides universal integration, high-performance motion control and safety-certified functions — making it the backbone of any precision automation setup.

Design & Functionality

Servo drives convert control commands from PLCs or motion controllers into electrical signals that power motors, ensuring optimal performance under varying loads and dynamic conditions. 

Festo offers multiple variants such as:
• Standard servo drive (CMMT-AS) for AC synchronous motors up to 12 kW power. 
• Compact servo drive (CMMT-ST) for low-voltage systems (24–48 V DC) and power ratings up to ~300 W. 
• Multi-protocol versions with EtherCAT®, PROFINET, Ethernet/IP and more for flexible system integration. 

These drives are engineered for high switching speed, precise motor control and easy commissioning via Festo Automation Suite or dedicated operating panels. 

⭐ Important: The broad variant range ensures you can match the drive to system size, voltage level, network topology and motion requirement.

Total Crossed Beams

This family of servo drives covers the full spectrum of motion-control tasks—from single-axis positioning to multi-axis interpolated systems, supporting both linear and rotary movements.

It ensures complete motion capability regardless of axis count, system architecture or integration complexity.

Designed to maintain stable performance, high precision and repeatability even under demanding industrial conditions.

Beam Pitch Options

Here the analogy translates to: power classes, bus protocols, motor compatibility and safety levels.

• Power classes: from small drives (hundreds of watts) up to high-power drives (several kilowatts) for heavy duty applications. 
• Bus / protocol options: EtherCAT®, Ethernet/IP, PROFINET, Modbus®, CANopen etc. 
• Safety features: built-in functions such as Safe Torque Off (STO), Safe Stop 1 (SS1), Safe Brake Control (SBC) up to SIL3/PL e. 
• Motor compatibility: supports Festo servo motors (EMMT-AS etc) and third-party motors with incremental or absolute encoders. 

⭐ Important: The wide selection of protocols, power ranges and safety options allows you to configure the drive exactly for your control system, motor size and performance requirement.

Intrinsic Synchronism

The internal control systems ensure perfectly synchronised motor commands and feedback processing, providing minimal latency, high resolution and tight loop control.

With multi-encoder inputs, dual-channel feedback and high-speed I/O, these drives support high-precision motion tasks and demanding positioning sequences. 

They also allow seamless integration into safety architectures and motion networks, synchronising multiple axes and ensuring coordinated system behaviour.
