🧩 What is SIMODRIVE 611

SIMODRIVE 611 is a modular digital drive system designed to control:

• Servo and spindle motors

• High-dynamic interpolated axes

• Synchronized multi-axis applications

The system is based on a rack architecture that integrates several functional modules:

• Power supply modules

• Power modules

• Control units

• Interface and communication boards

This modular structure has made SIMODRIVE 611 extremely flexible and adaptable even to highly complex machine configurations.
