The SINAMICS DC MASTER Control Module is mainly used for retrofitting and modernizing DC drives in existing plants and systems. There are many older DC installations in existence which cannot be linked to modern automation systems.

When such plants and systems are retrofitted or upgraded, the motor, mechanical system and power section are retained and only the closed-loop control section is replaced by a Control Module. As a consequence, an extremely favorably-priced modern DC drive is obtained with the full functional scope of the well-proven, fully digital units from the SINAMICS DC MASTER series.

The new system is adapted to the configuration of the existing components using simple parameterization.

The SINAMICS DC MASTER Control Module contains a power section for the field supply with a rated current of 40 A.
