General description

SINAMICS S150 cabinet units have been designed for variable-speed drives in machine building and plant construction. They are particularly suitable for use with variable-speed drives with high requirements regarding dynamic response and speed accuracy, frequent braking cycles with high braking energies, and four-quadrant operation.
SINAMICS S150 offers high-performance speed control with high accuracy and dynamic response.
The cabinet units are available for an output range from 75 kW to 1200 kW.


SINAMICS S150 are ready-to-connect converters in a standard control cabinet.
A comprehensive range of options permits adaptation to the respective requirements.
Different designs permit the power supply and motor connections to be located at the top or bottom. This results in high flexibility for the plant installation.
They are available with cabinet widths from 1400 mm upwards in intervals of 200 mm. The standard degree of protection of the cabinets is IP20. It can be optionally extended up to IP54.
The user-friendly AOP30 operator panel is fitted as standard in the cabinet door.

Customer benefits

Regenerative feedback as standard, therefore unrestricted four-quadrant operation possible

Significant energy savings, particularly with frequent braking cycles

Highly exact and highly dynamic mains supply through use of IGBTs; robust in the case of line voltage fluctuations

Injection of almost sinusoidal line current through fast current control

An innovative clean power filter means that low-frequency reactions on the system are almost negligible. Losses in the low-voltage distribution and/or mains transformer and in the power supply line resulting from harmonic currents are therefore also avoided

Possibility for compensation of reactive power (inductive or capacitive)

Maximum servicing friendliness with easy accessibility to all modules

Problem-free interfacing into automation solutions using a standard PROFIBUS interface and various analog and digital interfaces

Increase in plant availability through easy, fast replacement of individual modules and power components

Simple start-up and parameterization using interactive menus on the user-friendly AOP30 operator panel with LCD display incorporating graphics capability and plain text display

Typical applications

SINAMICS S150 is used wherever maximum requirements exist for process sequences with dynamic and reproducible procedures, e.g. :

Moving: Belt conveyors, cranes, test stands

Processing: Mechanical presses
