Distributed Servo drive SINAMICS S120M

Distributed Servo drive for Cabinetless Designs

SINAMICS S120M – Description


The modular SINAMICS S120 drive system has been expanded to include the distributed SINAMICS S120M version. This involves a compact ready-to-connect drive unit comprising:

  • Synchronous servomotor with multiturn absolute encoder

  • Integrated power unit (motor module)

The power unit has moved out of the control cabinet to the motor, and is directly integrated in the driven axis. This provides advantages and a high degree of flexibility regarding existing and new machine concepts.

An adapter module 600 (AM600) and a hybrid cable are required when using the SINAMICS S120M
