Benefits & applications

Servomotors for every motion task

Whether positioning, angular synchronism, cyclic drives or path control: With SIMOTICS servomotors from Siemens, you benefit from high dynamic performance, precision, compactness and ruggedness in sectors such as machine tools, robots and handling systems, packaging, plastics and textile machines along with wood, glass, ceramics and stone processing machines.

Benefits

  • High degree of efficiency and triple overload capability
  • High dynamic portfolio with an even lower intrinsic moment of inertia
  • Compact design regarding overall length and connection system
  • Low torque ripple: smooth running operation for good process quality
  • 22 bit encoder: absolute singleturn or multiturn as standard
  • Easy to mount using the rotatable plug connector with SPEED-CONNECT quick release coupling
  • Digital DRIVE-CLiQ interface with rugged M17 round connector
  • Optimal connection to SINAMICS S120 using an electronic nameplate

 

For demanding applications, S-1FT2 also offers the following benefits and additional options

  • High-resolution optical 26-bit encoder for even higher precision and dynamic performance
  • Optional versions for application conditions with increased environmental requirements
  • Increased maximum speeds
  • Additional optimized versions for higher and lower rated speeds
