1. Advanced Motion & Motor Control

• Dynamic Response: Features an optimized speed bandwidth of up to 
  
  
   and a rapid task cycle time of 
  
  
  , essential for machines requiring fast acceleration or precise settling times.
• Multi-Motor Support: Capable of driving standard asynchronous motors (in variable, constant, or optimized torque profiles) as well as high-efficiency synchronous motors like Permanent Magnet and Reluctance motors.
• Open & Closed Loop: Supports both control types to provide either standard industrial performance or high-precision position and speed regulation.
• Braking Management: Includes an integrated brake chopper and supports braking to standstill via DC injection for controlled stops.

3. Integrated Safety Functions

It eliminates the need for many external safety components by embedding certified safety logic: 

• Safe Torque Off (STO): Standard protection to prevent accidental motor restarts.
• Safely Limited Speed (SLS): Ensures the motor stays below a defined safe speed during maintenance or machine setup.
• Safe Brake Management (SBC/SBT): Integrated features for safe braking control, critical for hoisting and vertical load applications. 
  
  

4. Industrial Ruggedness

• Harsh Environments: Engineered to resist vibration, shock, and non-conductive dust.
• High Temperature: Capable of operating in ambient temperatures up to 
  
  
   (with derating).
• EMC Protection: Includes an integrated Class C3 EMC filter to reduce electromagnetic interference.
