The following power components are offered:
● Line-side power components, such as fuses, contactors, chokes and filters for switching
the energy supply and for observing the EMC regulations
● Line modules that perform the function of the central energy supply in the DC link
● DC link components used optionally for stabilizing the DC link voltage
● Motor modules that operate as inverter obtain their energy from the DC link and supply
the attached motors.
To handle the required functions, SINAMICS S120 has
● A control unit that processes the inter-axis drive and technological functions
● Additional system components to expand the functionality and to handle various
interfaces for encoders and process signals.
The SINAMICS S120 components have been developed for installation in control cabinets.
They are characterized by the following properties:
● Simple handling, simple installation and wiring
● Practice-oriented connection engineering and EMC-conform cable placement
● Consistent design, contiguous assembly
● Internal air cooling (other cooling methods on request).
