Servo Drives for Industrial Motion Control
High-performance drive solutions for cabinet-based, decentralized, embedded and long-lifecycle machine architectures.
Servo Drive Selection Overview
Our drive portfolio supports widely used fieldbus protocols, including EtherCAT, CANopen and PROFINET, together with motor feedback interfaces such as EnDat, BiSS-C, Hiperface and Tamagawa. Infranor also controls key manufacturing steps in France, with servo drives assembled and electronic boards produced and tested on site.
These drives can be combined with Infranor servomotors and the broader motion control product range. For sizing details, manuals and software resources, consult the technical documentation for each drive family.
How to Choose the Right Servo Drive
Selecting a drive depends on more than power rating. The right choice is determined by the machine architecture, supply voltage, peak current, fieldbus protocol, feedback device, safety requirements and integration constraints.
1. Define the machine architecture
Start with the physical integration: cabinet-mounted, decentralized, embedded, or battery-powered. This choice narrows the drive family before detailed sizing begins.
2. Check voltage and current requirements
Match the supply voltage, nominal current, and peak current to the axis duty cycle. Dynamic axes often need higher peak current margins than simple positioning axes.
3. Select the fieldbus protocol
Choose the drive interface according to the machine controller and network architecture, such as EtherCAT, PROFINET or CANopen.
4. Match the motor feedback interface
Confirm compatibility with the motor feedback device, including resolver, EnDat, BiSS-C, Hiperface, or Tamagawa interfaces where required.
5. Consider safety, environment and lifecycle constraints
Review safety functions, mounting environment, thermal constraints, service needs, and long-term availability before finalizing the drive architecture.

Advanced Servo Tuning and Servo-Loop Commissioning
For high-dynamic machines, standard auto-tuning may not be enough. Mechanical resonance, bandwidth limits and following-error validation can require a more controlled commissioning workflow.
Discover how PacHP and OPTIO support advanced servo tuning through machine-dynamics identification, bandwidth adjustment, resonance filtering and final motion validation.

Short answers to common questions about drive selection and integration.
How does a servo drive work?
A servo drive receives motion commands, checks motor feedback, and adjusts power to the servomotor in real time. This closed-loop control keeps the machine axis accurate, smooth and repeatable.

How do I choose the right Infranor servo drive?
Selection depends on the machine architecture, supply voltage, current requirements, fieldbus protocol, feedback interface, safety constraints and lifecycle expectations.
Which fieldbus protocols are supported?
Infranor servo drives support widely used industrial communication protocols including EtherCAT, CANopen and PROFINET, depending on the drive range and configuration.
Can Infranor servo drives be used with any servomotors?
Infranor servo drives are designed to work with Mavilor servomotors from the Infranor Group. They can also be integrated into broader servo-based motion control architectures depending on voltage, feedback and application requirements.
Which servo drive is suitable for mobile robotics?
For compact mobile robotics or robot-joint integration, IRD is the most relevant range because it is designed for decentralized DC architectures close to the motor. Easy 60Vdc is better suited to simpler low-voltage autonomous applications.
Where can I find technical documentation?
