Ohne Getriebe nur die halbe Lösung?

Only half the solution without a gear unit? Not with SEW‑EURODRIVE's modular system! You can opt to combine the CM3C.. series servomotor with a helical, parallel-shaft helical, helical-worm, helical-bevel or SPIROPLAN^® gear unit, or with a servo planetary gear unit from the PxG series.

Digital motor and data integration

MOVILINK DDI

Simple and fast motor startup with MOVILINK DDI

is possible thanks to the MOVILINK^® DDI digital interface. It's all based on single-cable technology. In fact, motors and inverters from the MOVI‑C^® modular automation system require just one hybrid cable for power supply and data transfer. The hybrid cable supplies the motor with power and MOVILINK^® DDI, a digital encoder, transfers all necessary power, brake and diagnostic data between inverter and motor. This saves you both time and money during installation and startup.

The digital motor and data integration works with synchronous motors, asynchronous motors and decentralized drive technology.

Functional safety overview

You can also request motors from the CM3C.. series with a safety brake and safety encoder. These can be integrated into the servomotor individually or in combination.
The following safety functions are possible with the safety brake:
- SBA (Safe Brake Actuation)
- SBH (Safe Brake Hold)
Using safety encoders, safety functions relating to rotational speed, direction of rotation, standstill and relative position are possible, such as SS1, SS2, SOS, SLA, SLS, SDI and SLI to IEC 61800‑5-2.
