The SINAMICS S150 represent Siemens’ solution for ultra-high-performance Motion Control, designed for industrial applications where high dynamics, absolute precision and continuous reliability are required.

The S150 series is intended for complex plants, advanced automatic machines and multi-axis systems, where motion control is a critical element of the production process.

SINAMICS G150 – Siemens maximum-power inverter for critical industrial applications

Siemens SINAMICS G150 inverters represent Siemens’ top-tier solution for controlling very high-power AC motors, designed for extremely critical, infrastructure-level industrial applications with high operational continuity requirements.

The G150 series is intended for plants where absolute reliability, advanced energy management, and safety are non-negotiable requirements.

SINAMICS G130 – High-power Siemens inverter (Heavy Duty)

Siemens SINAMICS G130 inverters are designed for the reliable control of high-power AC motors in heavy-duty industrial applications, where robustness, operational continuity, and precise control are required.

The G130 series is intended for complex plants and continuous processes, representing an intermediate solution between general-purpose inverters and maximum-power drive systems.

SINAMICS S120 – Motor Modules (6SL335x / 6SL336x)

The SINAMICS S120 Motor Modules represent the core of power conversion to the motor within the modular Siemens S120 architecture.
These modules are responsible for the precise control of current, torque, and speed of AC motors, ensuring high dynamics, reliability, and production continuity even in the most complex industrial processes.

Within SINAMICS S120 systems, Motor Modules work in synergy with:

• Line Modules (power supply and regeneration)

• Control Units (CU)

• SIMOTICS motors

creating a high-performance motion control ecosystem, typical of multi-axis and high-dynamic applications.

SINAMICS S120 – Line Modules and Power Line Units

SINAMICS S120 Line Modules represent the core of energy management in Siemens advanced drive systems.
Within the S120 architecture, these modules are responsible for supplying the DC link, managing energy regeneration, and ensuring electrical stability, safety, and operational continuity even in the most complex industrial applications.

The SINAMICS S120 – Line Modules / Power Line Units family is designed for multi-axis, motion control, and CNC applications, typical of SINUMERIK environments and advanced automation.

SINAMICS – SIMOREG DC Master: guide to the DC converters of the 6RA8 series…

The drives of the SIMOREG DC-MASTER family, 6RA8 series, represent Siemens’ most reliable and established solution for controlling direct current (DC) motors. Although they historically belong to the SIMOREG line, these products are often integrated into modern architectures that include SINAMICS converters, which is why we created a dedicated article referring to them jointly as SINAMICS SIMOREG.

Consistent with many industrial implementations, they can be considered part of an expanded Siemens drive ecosystem that combines AC and DC technologies within the same automation platform.

SINAMICS G120 – Power Modules and Control Units: Complete Technical Guide

The SINAMICS G120 family is one of Siemens’ most versatile and widely adopted solutions for industrial automation. Designed for general-purpose drive applications, the G120 combines power, modularity, energy efficiency, and seamless integration with Siemens control systems (SIMATIC, SINUMERIK, SIMOTION).

Modules belonging to the 6SL32xx root include Control Units, Power Modules, and Option Modules used across the G120, G120C, and G120X series, covering a wide range of needs—from industrial ventilation to pumps, conveyors, and process machinery.

SINAMICS S120 – Control Modules (Control Units / CU): the complete technical guide

The SINAMICS S120 system represents one of the most advanced Siemens drive architectures for complex motion-control applications. Used in machine tools, high-performance automation lines, packaging, extrusion, and multi-axis applications, the S120 stands out for its modularity, scalability, and seamless integration with SINUMERIK, SIMOTION, and Siemens PLCs.

Within the platform, the Control Modules (Control Units, CU) serve as the “brain” of the system: they manage drive logic, communication between modules, axis coordination, integrated safety, and the interface with PLCs and fieldbus networks.

Siemens Power Modules 6RB2000, 6RB2012 and 6RB2025

The Siemens 6RB2000, 6RB2012 and 6RB2025 modules belong to the SIMODRIVE family, specifically to the historical 6RB series, one of the first generations of Siemens industrial power supplies for drive systems. Although they predate the more well-known SIMODRIVE 611 platform, these modules remain essential in many legacy plants thanks to their reliability, robustness and ability to stabilize the DC bus.

They are widely used in applications where production continuity is a critical requirement and where a full plant revamping would involve high costs or extended downtime.

⚙️ Interface and connection modules for SIMODRIVE and SINUMERIK systems ⚙️

The 6FC9344, 6FC9348 and 6FX2001 roots belong to the family of interface, connection and communication modules used in SIMODRIVE and SINUMERIK systems to ensure stable and reliable data exchange between CNC, drives, peripherals and industrial networks.

These components do not directly manage power, but they are crucial for ensuring continuous and reliable machine communication.

⚙️ SINUMERIK / SIMODRIVE Interface Modules for CNC and Drive Integration ⚙️

The 6FC9320 root belongs to the SINUMERIK and SIMODRIVE ecosystem and is used as an interface and integration module between the numerical control (CNC) and drives in industrial automation systems.

It is therefore a cross-functional component, not a power unit, but essential for communication, synchronization, and the operational stability of the entire machine system.
