Features

SINAMICS S120 Combi offers maximum performance in minimum space:

Optimum dynamics and precision in a compact and integrated drive design - with valuable features such as Dynamic Servo Control (DSC), 80-bit NANO^FP accuracy and a high speed DRIVE-CLiQ communication interface
Uncompromising ruggedness - caused by optimum protection against condensation, insensibility against weak power supply, and protection against short circuit, overvoltage, and ground faults.
Perfectly expandibility - by easy connection of up to two additional SINAMICS S120 motor modules and by arbitrarily interpolation of the additional axes with the axes of SINAMICS S120 Combi.
