The new Sinamics S120 AC - not just a servo drive

This versatile drive now available from Micromech expands the existing Sinamics S120 system into an integrated modular drives system for single-axis and multi-axis applications

The new Siemens Sinamics S120 AC servo drive now available from Micromech expands the existing Sinamics S120 system into an integrated modular drives system for single-axis and multi-axis applications - as it also encompasses converters for high-performance single-axis applications.

Depending on the system voltage, the Sinamics S120 AC servo drives are rated at 1AC 230 V in the power range 0.12 to 0.75 kW, and at 3AC 400 V in the power range 0.37 to 250 kW.

The devices are available in block-style construction (0.12 to 90 kW) or as chassis devices (110 to 250 kW) according to the power rating.

The drives combine components for rectifier and power supply of the motor in one device, the power module - the PM340.

As a single-axis drive in combination with a higher-level controller, a control unit CU310 is plugged onto the power module.

This contains the entire closed-loop control intelligence, including the fieldbus interface and the positioning functions.

The control unit is available optionally with Profibus or Profinet interface.

The drive software is stored on a compact flash card and an optional, easy to use operator panel is available if required.

Within a drive solution along with other Sinamics S120 components, a control unit CUA31 adapter is plugged onto the power module.

In this way, the drive is connected to a higher-level control unit via a Drive-Cliq system interface.

The drives are used in all industry sectors, for example, in packaging, printing, centrifuges, elevators, extruders, mixers and kneaders.

Positioning tasks such as those found in automatic assembly machines and handling systems are also reliably solved.

Thanks to its modular design, the new drive type is equally suitable for multi-axis applications as it is for synchronous and motion control applications.

The configuration of these drives is supported by the clever Sizer dimensioning tool.

In addition the starter tool guarantees fast and safe start-up of the Sinamics S120 AC servo drives.

Safety functions are integrated direct in the drive.
